鍵入檢索詞

If you have little or no experience with Google, read on. Otherwise, skip to the next section, titled "Go to the First Result."

If your browser isn't pointing to Google, visit Google's home page by entering any one of the following web addresses into your browser:

Screen shot of Google's home page.
When I refer to a web address in this tutorial, I omit the "http://" prefix. For a description of web addresses, see the section "Anatomy of a Web Address."

What is a query? It's a request for information from a search engine. A query consists of one or more words, numbers, or phrases that you hope you will find in the search results listings. In Google Guide, I sometimes call a query search terms.

To enter a query, type in descriptive words into Google's search box. You can use either the search box on Google's home page (shown above) or the search box that always appears at the top of a Google results page (shown in the next screen shot).

Now press the ENTER key or click on the "Google Search" button to view your search results, which include links to pages that match your query along with relevant snippets (excerpts) with your search terms in a boldface.

  

This example isn't just a picture of what the search box looks like. If you click the "Google Search" button, you'll go to the Google results page for a search on the words "california" and "driving." Feel free to edit what's in the search box and run other searches.

Screen shot of Google search results for "california driving"

The results page is full of information and links most of which relate to your query. In this screen shot, to the right of Google's search results appear sponsored links, which are paid advertisements. Results Google considers to be most relevant to your query are shown first.

To view a page listed in your search results, click on the page title, the first line in each result. Any of your query words that appear in the title will be in boldface, and the title will be underlined, i.e., it's a link to the web page. Note that when you position your mouse pointer on the title, the URL for the web page will appear in your browser's status bar, at the bottom of many browsers. Under the title will be excerpts that include one or more of your query words: your query words will be in boldface. These excerpts are known as snippets. In our example, click on the California Driving -- A Survival Guide link, which appears just below the blue bar with the text "Searched the web for california driving," to view the corresponding California Driving Guide web page.

Your results for a search on "california driving" may be different from what you see here since Google is constantly searching the Web for new pages and adjusting its results algorithms.

好手氣

Click on the I'm Feeling Lucky button on Google's home page to go directly to the first result for your query. Instead of showing you a list of pages, Google sends you immediately to the result that may be most relevant to your query. For example, if you enter the query [ california driving ] (without the square brackets) and click the I'm Feeling Lucky button, Google will send you to the home page of Hamish Reid's wonderful California Driving Guide.

Google search box with [ california driving ].  

This example isn't just a picture of what a search box and the I'm Feeling Lucky button look like. In this example and in others like it throughout this tutorial, you can edit what's in the search box and run different searches.

Screen shot of the top result from search for "california driving"

The I'm Feeling Lucky button can save you the time it takes to review your results and then click on the first one. Use it when you're confident the page you want is the best fit for your query, which is usually the case when you're seeking very popular pages. For example, it's a safe bet that an I'm Feeling Lucky search for "Paul McCartney" (one of The Beatles) will send you to his home page www.paulmccartney.com.

Note: I'm Feeling Lucky doesn't consider the various sponsored links on the first results page, which are paid advertisements, when deciding where to take you. In other words, the I'm Feeling Lucky button will send you to what Google considers the most relevant result that is not a paid advertisement.

In the Section after the Exercises, we'll look at how to select search terms.

For simplicity sake, this tutorial uses square brackets to denote Google's search box. For example, to search for a cheap hotel in Mykonos, I'll put the words "cheap," "hotel," and "Mykonos" in square brackets, [ cheap hotel Mykonos ], to indicate you should type those three words in Google's search box. You should not type the brackets, although Google will ignore them if you do type them.

Furthermore, in the examples that follow, I have linked each set of search terms to the results of doing a Google search on those terms. So clicking on [ cheap Mykonos hotel ] returns the Google results page for a search on those three words.

鍵入網頁內可能出現的字詞

[ salary negotiation tips ]
[ sciatica ]
[ window treatments ]

不要使用問句, For example, the query, [ where do I apply for a passport in New Zealand ], instructs Google to find pages containing all the terms. Such a query won't necessarily find pages answering your question. A better query might be [ passport apply New Zealand ].

USE [ passport apply New Zealand ]
NOT [ where do I apply for a passport in New Zealand ]

出現頻率太高的常用字, 被視為高頻字, 被 Google 忽視, 以免找出不相關的結果; 一定要檢索這些字詞時, 應參照 complete phrase or a specific word in the section Crafting Your Query.

Avoid using words that you might associate with your topic, but you wouldn't expect to find on the designated page(s). For example, queries that include "articles about," "discussion of," "documentation on," and "pages about" are likely to return fewer results since information on the web is rarely labeled with such terms.

USE [ lasik eye surgery ]
NOT [ documentation on lasik eye surgery ]

USE [ jobs product marketing Sunnyvale ]
NOT [ listings of product marketing jobs in Sunnyvale ]

Suppose you want to know how old someone is, such as Nelson Mandela (the former President of South Africa). Pages with "birthday" or "age" might be more than a year old. Searching for pages that include "Nelson Mandela" and "born" are likely to include either "Nelson Mandela born" or "Nelson Mandela was born" followed by his birth date. You can figure out his age from knowing when he was born.

USE [ Nelson Mandela born ]
NOT [ Nelson Mandela birthday ] nor [ Nelson Mandela age ]

Note: The section How Google Works describes how Google finds web pages and constructs an index.

精確檢索: 以多個鍵詞縮小檢索結果

It's better to use a more precise, less ambiguous term than a common one to "flesh out the topic by including facets that interest you," notes Ned Fielden in his book Internet Research, Second Edition (McFarland & Company, 2001).

Does your query have enough specific information for Google to determine unambiguously what you're seeking? If your query is too vague, it's unlikely to return relevant results. Consider, for example, the query [ java ]. What do you suppose Google includes in the first page of results? An island in Indonesia? A beverage consisting of an infusion of ground coffee beans? A computer network-oriented platform-independent programming language developed by Sun Microsystems?

USE [ Java Indonesia ], [ java coffee ], or [ java programming language ]
NOT [ java ]

How can you come up with more specific search terms? What do you know about the topic? Consider answers to the questions, who?, what?, where?, when?, why?, and how?

有三大名人都是 Tom Watson, 單獨鍵入 [ Tom Watson ], 能夠符合期望的機會, 祗有三分之一。on the first page of results you get references to a member of Parliament, the golfer, the IBM executive, and a Populist Party candidate for President in 1900 and 1904. If you're searching for something that could return many different types of results, you should add a term that distinguishes among them. This way you'll get only results about the specific Tom Watson you're interested in.

USE [ Tom Watson MP ], [ Tom Watson golf ], or [ Tom Watson IBM ]
NOT [ Tom Watson ]

USE [ baby development ] or [ baby milestones ]
NOT [ babies ]

USE [ Betty Ford Center drug addiction ]
NOT [ Ford Center ]

Note: Google 的鍵詞必須在32個字之內

簡潔

Forr best results, use a few precise words. For example, a program on quitting smoking is more likely to include the terms "quit smoking program" than the words "program on quitting tobacco cigarette smoking addiction."

USE [ quit smoking program ]
NOT [ program on quitting tobacco cigarette smoking addiction ]

拚錯字沒關係

there's a good chance that Google will recognize your mistakes and suggest an alternative more common spelling, usually faster than you can look up the term in an online dictionary.

When you enter: [ Anna Kornikova tennis ]
Google responds: Did you mean: Anna Kournikova tennis

Note: Before clicking on Google's suggested spelling, consider whether it's what you want. Spelling checker, like people, make mistakes.

For more information on Google's spelling correction system, see the section Spelling Corrections.

Note: Even if you use the search tips described in Google Guide, you won't be able to access authoritative information that's available offline, e.g., old reference books, or is stored in specialized databases. For such information is not currently searchable with Google.

Next we'll look at how Google interprets your query.

解讀鍵詞

Understanding how Google treats your search terms will help you devise effective queries and revise ineffective ones.

祗回應符合全部鍵 詞的網頁

A search for [ compact fold-up bicycle ] finds pages containing the words "compact" and "fold-up" and "bicycle." Because you don't need to include the word AND between your terms, this notation is called an implicit AND.

[ compact fold-up bicycle ]

Because of implicit AND, you can focus your query by adding more terms.

[ compact lightweight fold-up bicycle ]

Note: If you want pages containing any (instead of all) of your search terms, use the OR operator, which is described in the next section Crafting Your Query.

Note: Google sometimes returns pages that don't contain your query terms, as you can see in the example in the Cached Pages section in Part II. Google returns pages in which your query terms are included in the link text (interpreted as a description) to another page or place on the page, more commonly referred to as the anchor text of a link pointing to the page.

精準回應符合鍵詞的網頁

In his book Internet Research, Second Edition (McFarland & Company, 2001), Ned Fielden notes "Google simply matches strings of characters together and doesn't currently base inferences on uses of the language. Although this searching method has some drawbacks, it harnesses one of the fabulous powers of computers, [the ability] to sift through enormous heaps of data quickly and accurately."

 If you search for ...  Google won't find ...

回應鍵詞的變化詞

The query [ child bicycle helmet ] finds pages that contain words that are similar to some or all of your search terms, e.g., "child," "children," or "children's," "bicycle" "bicycles," "bicycle's," "bicycling," or "bicyclists," and "helmet" or "helmets." Google calls this feature word variations or automatic stemming. Stemming is a technique to search on the stem or root of a word that can have multiple endings.

If you only want to search for pages that contain some term(s) exactly, precede each such term with a plus sign (+) or enclose more than one term in quotes (" ").

Google doesn't match variants when your query consists of a single term.

Note: When you want synonyms or variants that Google doesn't find, consider using either the OR or tilde operator, which is described in the next section Crafting Your Query.

忽略使用頻率 高的 "高頻字"; e.g., the, on, where, how, de, la, as well as certain single digits and single letters.

Stop words tend to slow down your search without improving the results. Google will indicate if a stop word has been excluded on the results page below the search box.

[ lyrics to the Dixie Chicks' songs ]

Screen shot showing what Google does when it ignores some common words, such as "to" and "the."

Note: Use the + operator or enclose more than one term in quotes (" ") to force Google to include terms it would otherwise ignore. I describe these basic operators and others in the next section, 6 Crafting Your Query.

If your query consists only of common words that Google normally ignores, Google will search for pages that match all the terms.

[ the who ]

Note: Find more pages mentioning the rock band The Who by entering [ "the who" ], a notation you'll learn about in the next section Crafting Your Query.

的鍵詞以32個字為限

Google will indicate in a message below the query box at the top of the page if your query exceeds the 32-word limit. The 32-word limit applies to search terms and operators but not stop words.

The limit was previously 10 words, as shown in the following image.

Screen shot of Google message indicating 10-word limit.

The following query finds sites that have included Google Guide's description of how Google works.

[ "Google consists of three distinct parts, each of which is run on a distributed network of thousands of low-cost computers and can therefore carry out fast parallel processing. Parallel processing is a method of computation in which many calculations can be performed simultaneously, significantly speeding up data processing." ]

偏好鍵詞臨近的結果

Google considers the proximity of your search terms within a page. So the query [ snake grass ] finds pages about a plant of that name, while [ snake in the grass ] tends to emphasize pages about sneaky people. Although Google ignores the words "in" and "the," (these are stop words), Google gives higher priority to pages in which "snake" and "grass" are separated by two words.

[ snake grass ]
[ snake in the grass ]

Note: The description of a wildcard in the section Craft Your Query may help you to understand how Google interprets queries containing words that it ignores.

鍵詞順序相同的網頁有較高的排序

Consequently, you should enter search terms in the order in which you would expect to find them on the pages you're seeking. A search for [ New York library ] gives priority to pages about New York's libraries. While the query [ new library of York ] gives priority to pages about the new libraries in York.

[ New York library ]
[ new library of York ]

大小寫無分別

Ignoring case distinctions increases the number of results Google finds. A search for [ Red Cross ] finds pages containing "Red Cross," "red cross," or "RED CROSS."

[ Red Cross ], [ red cross ], and [ RED CROSS ] return the same results

There is no way to instruct Google to pay attention to case distinctions, e.g., you can't tell Google to find only occurrences of "Red Cross" where the first letter of each word is capitalized.

Note: The words "OR" and "AND" have special meanings if entered in uppercase letters.

忽略部份標點符號及特殊字元, 如: ! ? , . ; [ ] @ / # < > .

Because punctuation is typically not as important as the text around it, Google ignores most punctuation in your search terms. There are exceptions, e.g., C++ and $99. Mathematical symbols, such as /, <, and >, are not ignored by Google's calculator.

Dr. Ruth ] returns the same results as [ Dr Ruth ]

What if you're seeking information that includes punctuation that Google ignores, e.g., an email address? Just enter the whole thing including the punctuation.

info@amazon.com ]

Be aware that web pages sometimes camouflage email addresses to make collecting such information difficult for spammers. For example, on some sites you'll find the @ sign in an email address replaced with the word "at."

Now we'll look at some special characters that Google doesn't ignore.

接受單點省略符號

A query with the term "we're" returns different results from a query with the term "were."

we're ] matches "we're" but not "were"
were ] matches "were" but not "we're"

接受讀音符號

"A diacritic is a mark, such as the cedilla of façade or the acute accent of resumé, added to a letter to indicate a special phonetic value or distinguish words that are otherwise graphically identical," according to Dictionary.com.

Schröder] matches "Schröder" but not "Schroder" nor "Schroeder"
Schroeder] matches "Schroeder" but not Schröder" nor "Schroder"
Schroder] matches "Schroder" but not Schröder" nor "Schroeder"

Côte d'Ivoire ] matches "Côte d'Ivoire" but not "Cote d'Ivoire"
Cote d'Ivoire ] matches "Cote d'Ivoire" but not "Côte d'Ivoire"

mañana ] matches "mañana" but not "manana"
manana ] matches "manana" but not "mañana"

If you want pages containing either "mañana" or "manana", use the OR operator, which is described in the section Crafting Your Query.

Note: For queries with diacritics, results vary depending on the language to which you are confining your search. For example, when I search for Martín (a Spanish name), the US version of Google returns only pages that include "Martín" but when I restrict my search to pages in Spanish, Google returns pages that include either "Martín" or "Martin.".

Search all pages: [ Martín ] matches "Martín"  but not "Martin"
Search Spanish pages: [ Martín ] matches "Martín"  and "Martin"

連接號、空格及無任何符號均同義

When Google encounters a hyphen (-) in a query term, e.g., [ part-time ], it searches for:

[ part-time ] matches "part-time," "part time," and "parttime"
[ part time ] matches "part-time" and "part time"

[ e-mail ] matches "e-mail," "email," and "e mail"
[ email ] matches "email"

If you aren't sure whether a word is hyphenated, go ahead and search for it with a hyphen.

Search Behaviors  Descriptions
Implicit AND Google returns pages that match all your search terms. Because you don't need to include the logical operator AND between your terms, this notation is called an implicit AND.
Exact Matching Google returns pages that match your search terms exactly.
Word Variation
Automatic Stemming
Google returns pages that match variants of your search terms.
Common-Word Exclusion Google ignores some common words called "stop words," e.g., the, on, where, and how. Stop words tend to slow down searches without improving results.
32-Word Limit Google limits queries to 32 words.
Term Proximity Google gives more priority to pages that have search terms near to each other.
Term Order Google gives more priority to pages that have search terms in the same order as the query.
Case Insensitivity Google is case-insensitive; it assumes all search terms are lowercase.
Ignoring Punctuation Google ignores most punctuation and special characters including , . ; ? [ ] ( ) @ / * < >
Accented Letters A term with an accent doesn't match a term without an accent and vice versa.

以特殊字元修正檢索

By using special characters and operators, such as +, -, ~, .., *, OR, and quotation marks, you can fine-tune your search query and increase the accuracy of its results.

To search for a phrase, a proper name, or a set of words in a specific order, put them in double quotes.

A query with terms in quotes finds pages containing the exact quoted phrase. For example, [ "Larry Page" ] finds pages containing exactly the phrase "Larry Page." So this query would find pages mentioning Google's co-founder Larry Page, but not pages containing "Larry has a home page" or "Congressional page Larry Smith." The query [ Larry Page ] (without quotes) would find pages containing any of "Larry Page," "Larry has a home page," or "Congressional page Larry Smith."

[ "Larry Page" ]
[ Larry Page ]

A quoted phrase is the most widely used type of special search syntax.

[ "close your eyes and I'll kiss you" ]
[ "what you're looking for is already inside you" Anne Lamott speech ]

Use quotes to enter proper names.

[ "Julia Robinson" ]
[ "Rio de Janeiro" ]

Find recommendations by searching for pages containing lists.

[ "favorite movies" ]
[ "best non-fiction books" ]

引號內的高頻字被 檢 索出來

USE [ "to be or not to be" ]
NOT [ to be or not to be ]

USE [ "how to change oil" ]
NOT [ how to change oil ]

不會自動截斷 句子, i.e., searching for pages that match variants of any of your search terms, which I described in the previous section Interpret Your Query. For example, if you want to see pages that mention only one favorite book rather than lists of favorite books, enclose your search terms in quotes.

[ "favorite book" ]

教師以特殊的字句做為學生抄襲的依據Some teachers use quoted phrases to detect plagiarism. They copy a few unique and specific phrases into the Google search box, surround them with quotes, and see if any results are too similar to their student's supposedly original work. Find ways to detect and prevent plagiarism.

[ "ways to detect plagiarism" ]
[ "how to detect plagiarism" ]

You may include more than one quoted string in a query. All quoted query phrases must appear on a result page; the implied AND works on both individual words and quoted phrases.

[ "The Cat in the Hat" "Green Eggs and Ham"  ]

Note: You'll learn how to find a page by specifying its title in the section Using Search Operators.

強迫接受特別的鍵詞Force Google to include a term by preceding the term with a "+" sign.

To force Google to search for a particular term, put a + sign operator in front of the word in the query. Note that you should not put a space between the + and the word, i.e. [ +The Beatles ], not [ + The Beatles ].

The + operator is typically used in front of stop words that Google would otherwise ignore or when you want Google to return only those pages that match your search terms exactly. However, the + operator can be used on any term.

Want to learn about Star Wars Episode One? "I" is a stop word and is not included in a search unless you precede it with a + sign.

USE [ Star Wars +I ]
NOT [ Star Wars I ]

Google excludes common words in English and in other languages, such as "la" (which means "the" in Spanish) and "de" (which means "of" in French, Spanish, Italian, and Portuguese). So if Google ignores a term critical to your search, e.g., LA (common abbreviation for Los Angeles), put a + sign in front of it.

USE [ jobs in central +LA California ]
NOT [ jobs in central LA California ]

The query [ jobs in central LA California ] finds jobs in central California, since the term "LA" is ignored because it's a stop word. Central California is at least a hundred miles (160 km) from central Los Angeles.

Disable automatic stemming, i.e., searching for pages that match variants of your search term(s), by preceding each term that you want to be matched exactly with the + operator. For example, if you want to see only pages mentioning one favorite book rather than lists of favorite books, precede the word "book" by a + sign.

[ favorite +book ]

What if you're looking for a string that contains a "+" sign? Though the character has special meaning, Google gives special attention to very common terms that include it, e.g., C++ (the name of a widely used computer language).

[ C++ ]

以減號做差集運算

To find pages withouta particular term, put a -sign operator in front of the word in the query. The -sign indicates that you want to subtract or exclude pages that contain a specific term. Do not put a space between the -and the word, i.e. [ dolphins -football ] not [ dolphins  - football ].

So, to search for a twins support group in Minnesota, but not return pages relating to the Minnesota Twins baseball team:

USE [ twins support group Minnesota -baseball ]
NOT [ twins support group Minnesota ]

No pages containing the word "baseball" will be returned by the first query.

Find pages on "salsa" but not the dance nor dance classes.

USE [ salsa -dance -class ]
NOT [ salsa ]

以波浪號做同義字檢索

The tilde (~) operator takes the word immediately following it and searches both for that specific word and for the word's synonyms. It also searches for the term with alternative endings. The tilde operator works best when applied to general terms and terms with many synonyms. As with the + and - operators, put the ~ (tilde) next to the word, with no spaces between the ~ and its associated word, i.e., [ ~lightweight laptop ] not [ ~ lightweight laptop ].

Why did Google use tilde? In math, the "~" symbol means "is similar to ". The tilde tells Google to search for pages that are synonyms or similar to the term that follows.

~inexpensive ] matches "inexpensive," "cheap," "affordable," and "low cost"
[ ~run ] matches "run," "runner's," "running," as well as "marathon"

Looking for a guide, help, tutorial, or tips on using Google?

google ~guide ]

Interested in food facts as well as nutrition and cooking information?

[ ~food ~facts ]

The synonym operator tends not to work well on well-defined terms.

[ ~cockroach ]

If you don't like the synonyms that Google suggests when you use the ~ operator, specify your own synonyms with the OR operator, which I describe next.

Note: Google offers a link to a dictionary and a thesaurus.

以 OR 或 | (垂直線)做聯集運算

The OR operator, which you may abbreviate with | (vertical bar), applies to the search terms immediately adjacent to it. The first example will find pages that include either "Tahiti" or "Hawaii" or both terms, but not pages that contain neither "Tahiti" nor "Hawaii."

[ Tahiti OR Hawaii ] or [ Tahiti | Hawaii ]
[ blouse OR shirt OR chemise ] or [ blouse | shirt | chemise ]

Note: If you write OR with a lowercase "o" or a lowercase "r," Google interprets the word as a search term instead of an operator.

Note: Unlike OR, a | (vertical bar) need not be surrounded by spaces.

[ bicycle|cycle ]

Use quotes (" ") to group compound words and phrases together.

[ "New Zealand" OR "Ivory Coast" holiday package ]
[ filter OR stop "junk email" OR spam ]

Google considers terms with accents different from those without. For example, Google interprets "côte" and "cote" as different terms and indexes them separately. To ensure that you retrieve many relevant pages, include all possible spellings separated by OR.

[ "Ivory Coast" OR "Côte d'Ivoire" OR "Cote d'Ivoire" ]

檢索介於兩個數字之間的值

以兩個圓點連結此二數字

For example, specify that you are searching in the price range $250 to $1000 using the number range specification $250..$1000.

recumbant bicycle $250..$1000 ]

以星號為萬用字元, 代表引號內鍵詞的任何字

Each * represents just one word. Google treats the * as a placeholder for a word. For example, [ "Google * my life" ] tells Google to find pages containing a phrase that starts with "Google" followed by a word, followed by "my life." Phrases that fit the bill include: "Google changed my life," "Google runs my life," and "Google is my life."

"Google * my life" ]

If you know there's a date on the page you're seeking but you don't know its format, specify several common formats. For example:

[ California election "Oct * 2003" OR "10/*/03" OR "October * 2003" ]

When you know only part of the phrase you wish to find, consider using the * operator. Find the title of Sherry Russell's book that can help you deal with the tragedies of 9/11 or losing a loved one.

"Conquering the * and * of Grief" ]

You can use the symbol * to search for terms that are a specified number of words from each other on any page (see below for examples specifying the number of words). This type of searching, known as proximity searching, is great when you know the start and end of a title or quote, but are unsure of the words in between. By trying each of these searches you will find the answer:

"Conquering the * Grief" ]
"Conquering the * * Grief" ]
"Conquering the * * * Grief" ]
"Conquering the * * * * Grief" ]
"Conquering the * * * * * Grief" ]
"Conquering the * * * * * * Grief" ]
"Conquering the * * * * * * * Grief" ]
"Conquering the * * * * * * * * Grief" ]

Proximity searching can be useful when you want to find pages that include someone's name in any of the following orders: first middle last, last first middle, first last, last first. To search for "Francis" adjacent or separated one word from "Coppola," requires four queries:

"Francis Coppola" ]
"Francis * Coppola" ]
"Coppola Francis" ]
"Coppola * Francis" ]

If you want to search for two terms separated by no more than two words, you'll need six queries. If you're interested in running proximity searches, try out GAPS, a third-party search tool available at http://www.staggernation.com/cgi-bin/gaps.cgi.

Screen shot of GAPS form.

Note: You can get around Google's 10-word limit on the number of words in your query by substituting an * in place of each stop word or common word in your query. Wildcards are not counted.

USE [ All grown-ups * once children--although few * them remember * ]
NOT [ All grown-ups were once children--although few of them remember it ]

Google chose the symbol * to match any word because in some computer systems, such as Unix, Linux, and DOS, * stands for one or more unspecified characters. In those languages it is typically used for selecting multiple files and directories.

Note: Stemming is a technique to search on the stem or root of a word that can have multiple endings. For example, on some search engines the query bicycl* will return results that match words including bicycle, bicycles, bicycling, bicycled, and bicyclists. Google ignores asterisks (*) that are not surrounded by spaces. The query [ bicycl* ] finds documents that contain "bicycl." Google automatically provides stemming.

This table summarizes how to use the basic search operators, described on this page. You may include any of these operators multiple times in a query.

Notation Find result Example
terms1 terms2 with both term1 and term2 [ carry-on luggage ]
term1 OR term2
term1 | term2
with either term1 or term2 or both [ Tahiti OR Hawaii ]
[ Tahiti | Hawaii ]
+term with term (The + operator is typically used in front of stop words that Google would otherwise ignore or when you want Google to return only pages that match your search terms exactly. However, the + operator can be used on any terms.) [ +i spy ]
-term without term [ twins minnesota -baseball ]
~term with term or one of its synonyms
(currently supported on Web and Directory search)
[ google ~guide ]
number1..number2 with a number in the specified range
recumbant bicycle $250..$1000 ]
"phrase"  with the exact phrase, a proper name, or a set of words in a specific order [ "I have a dream" ]
[ "Rio de Janeiro" ]
"terms1 * terms2" with the phrase (enclosed in quotes) and * replaced by any single word [ "Google * my life" ]

Queries that use Google's special notation may also be entered by using Google's Advanced Search, which we'll look at next.

以進階搜尋表單縮小查詢範圍

When you don't find what you're seeking, consider specifying more precisely what you want by using Google's Advanced Search feature. Don't be frightened by the name "Advanced Search"; it's easy to use, and it allows you to select or exclude pages with more precision than Google's standard search box. Click on the Advanced Search link, which is located to the right of Google's search box

or visit www.google.com/advanced_search and fill in the form. The Advanced Search form is automatically filled in with appropriate information from your previous query — if you entered a query just before you clicked on the Advanced Search link. If you searched for a phrase, the phrase appears in the phrase search box. If you restricted your search to a specific site or domain, the domain appears in the domain box.

搜尋特定網頁

The Advanced Search form also offers page-specific searches for finding pages similar to a page for which you have a web address (URL) and for finding out what pages link to a particular page.

Unlike the other fields in the Advanced Search form, the page-specific searches can't be combined with other query terms. Consequently each has its own Search button.

You can easily run these page-specific searches from Google's Toolbar, which is described in the section Making Google Easier with Google Tools.

Instead of going to the Advanced Search form, you can search for a web site by entering its address in the search box and Google returns a link to the website, as well as links to:

For example, to find out about the wonderful reference site www.refdesk.com, enter www.refdesk.com into Google's search box.

修正鍵詞

Refining a query means changing or adding to the set of search terms to do a better job of returning the pages you're seeking. Successful researchers frequently enter several queries to find what they're seeking.

The search boxes at the top and bottom of the results page show the query for the current results page. If the query uses special operators that you entered either directly or indirectly through the advanced search form, they will appear in the search box as well. To refine your query, edit what's in the search box and then click the "Google Search" button or hit the ENTER key.

Let's look at a few examples.

The following table presents suggestions to narrow or focus a search, as well as tips for broadening a search that has produced few useful results. Click on a link in the table to be taken to the section in Google Guide that describes features and ways to refine your query.

Too many results? Focus the search by... Too few results? Broaden the search by...
adding a word or phrase removing a word or phrase
specifying the order in which you want words to appear specifying words instead of phrases
using a more specific term using more general terms
identifying ineffective terms and removing them including synonyms or variant word forms or using a more common version of the word's spelling
limiting to a domain or site broadening the domain or searching the entire web
limiting to a date range or including a date removing a date range
limiting where terms occur removing redundant terms or splitting a multi-part query
restricting type of file searching any type of file
limiting pages in a particular language translating your search terms into other languages and searching for the translated terms
limiting pages to a particular country searching the entire web

剖析網域

If you already know how to read a web address or URL (pronounced "you are ell" and stands for Universal Resource Locator), skip this section. A website is usually the host or server between the http:// and the first /. Consider the web address http://www.googleguide.com/searchEngines/google/searchLeader.html. (This page lists reasons why Google is a search leader.) Here's what it all means:

http   transfer protocol (type of information being transferred)
www.googleguide.com    site name
googleguide    second-level domain name
com    top-level domain name
searchEngines    directory name
google    sub-directory name
searchLeader    file name
html    file format

Here's a list of some common top-level domain names:

.edu    educational site (usually a university or college)
.com    commercial business site
.gov    U.S. government/non-military site
.mil    U.S. military sites or agencies
.net    networks, Internet service providers, organizations 
.org    U.S. non-profit organizations and others

Because the Internet was created in the United States, "US" was not originally assigned to U.S. domain names; however, it's used to designate American state and local government hosts, including many public schools, and commercial entities, e.g., well.sf.ca.us. The domain .ca represents Canada, unless it's followed by .us, in which case it represents California.

Domain
Codes
  State
.ca.us  California
.nv.us  Nevada
.tx.us  Texas

Other countries have their own two letter codes as the top level of their domain names.

Codes
  Country
.ca    Canada  
.de    Germany  
.dk    Denmark  
.jp    Japan  
.il    Israel  
.uk    United Kingdom

To limit results to a single site or domain, specify the site name (e.g., www.googleguide.com or googleguide.com) or a top-level domain name (e.g., .com or .edu) in Google's domain selector.

使用蒐尋運算元 (進階運算元)

Skip to Part II: Understanding Search Result unless you're an experienced Google user or you want to know how to use Google's advanced operators.

You can specify most of the Advanced Search page options in a regular search box query by using advanced operators, i.e., query words that have special meaning to Google. Since the advanced operators are convenient for searching, Google Guide calls them "search operators."

Want to see examples of search operators? Visit the Google Guide Advanced Operator Quick Reference or fill in the Advanced Search form. Now, look at the search box on the results page. Your query may now include special notation or special operators of the form operator:value.

Note: The colon following the operator name is mandatory.

[ Larry Page search engine site:stanford.edu ]
[ volunteering site:.org ]
[ link:www.doctorswithoutborders.org ]
[ allintitle: detect plagiarism ]
[ Google tutorial OR introduction OR overview OR help ]
[ bush -george -kate ]
[ web page evaluation checklist filetype:pdf ]

The following table lists features available on the Advanced Search page that are accessible via search operators.

The following is an alphabetical list of the search operators. This list includes operators that are not in Google's online help. Each entry typically includes the syntax, the capabilities, and an example. Some of the search operators won't work as intended if you put a space between the ":" and the subsequent query word. If you don't care to check which search operators require no space after the colon, always place the keyword immediately next to the colon. Many search operators can appear anywhere in your query. In our examples, I placed the search operator as far to the right as possible. We did this since the Advanced Search form writes queries in this way. Also, such a convention makes it clearer as to which operators are associated with which terms.

allinanchor:
If you start your query with allinanchor:, Google restricts results to pages containing all query terms you specify in the anchor text on links to the page. For example, [ allinanchor: best museums sydney ] will return only pages in which the anchor text on links to the pages contain the words "best," "museums," and "sydney."

Anchor text is the text on a page that is linked to another web page or a different place on the current page. When you click on anchor text, you will be taken to the page or place on the page to which it is linked. When using allinanchor: in your query, do not include any other search operators. The functionality of allinanchor: is also available through the Advanced Web Search page, under Occurrences.

allintext:
If you start your query with allintext:, Google restricts results to those containing all the query terms you specify in the text of the page. For example, [ allintext: travel packing list ] will return only pages in which the words "travel," "packing," and "list" appear in the text of the page. This functionality can also be obtained through the Advanced Web Search page, under Occurrences.
allintitle:
If you start your query with allintitle:, Google restricts results to those containing all the query terms you specify in the title. For example, [ allintitle: detect plagiarism ] will return only documents that contain the words "detect" and "plagiarism" in the title. This functionality can also be obtained through the Advanced Web Search page, under Occurrences.

In Image Search, the operator allintitle: will return images in files whose names contain the terms that you specify.

In Google News, the operator allintitle: will return articles whose titles include the terms you specify.

allinurl:
If you start your query with allinurl:, Google restricts results to those containing all the query terms you specify in the URL. For example, [ allinurl: google faq ] will return only documents that contain the words "google" and "faq" in the URL. This functionality can also be obtained through the Advanced Web Search page, under Occurrences.

In URLs, words are often run together. They need not be run together when you're using allinurl:.

In Google News, the operator allinurl: will return articles whose titles include the terms you specify.

author:
If you include author: in your query, Google will restrict your Google Groups results to include newsgroup articles by the author you specify. The author can be a full or partial name or email address. For example, [ children author:john author:doe ] or [ children author:doe@someaddress.com ] return articles that contain the word "children" written by John Doe or doe@someaddress.com.

Google will search for exactly what you specify. If your query contains [ author:"John Doe" ], Google won't find articles where the author is specified as "Doe, John."

bphonebook:
If you start your query with bphonebook:, Google shows business white page listings for the query terms you specify. For example, [ bphonebook: google mountain view ] will show the phonebook listing for Google in Mountain View.
cache:
The query cache:url will display Google's cached version of a web page, instead of the current version of the page. For example, [ cache:www.eff.org ] will show Google's cached version of the Electronic Frontier Foundation home page.

Note: Do not put a space between cache: and the URL (web address).

On the cached version of a page, Google will highlight terms in your query that appear after the cache: search operator. For example, [ cache:www.pandemonia.com/flying/ fly diary ] will show Google's cached version of Flight Diary in which Hamish Reid's documents what's involved in learning how to fly with the terms "fly" and "diary" highlighted.

define:
If you start your query with define:, Google shows definitions from pages on the web for the term that follows. This advanced search operator is useful for finding definitions of words, phrases, and acronyms. For example, [ define: blog ] will show definitions for "Blog" (weB LOG).
ext:
This is an undocumented alias for filetype:.
filetype:
If you include filetype:suffix in your query, Google will restrict the results to pages whose names end in suffix. For example, [ web page evaluation checklist filetype:pdf ] will return Adobe Acrobat pdf files that match the terms "web," "page," "evaluation," and "checklist." You can restrict the results to pages whose names end with pdf and doc by using the OR operator, e.g. [  email security filetype:pdf OR filetype:doc ].

When you don't specify a File Format in the Advanced Search Form or the filetype: operator, Google searches a variety of file formats, see the table in the File Type Conversion section.

group:
If you include group: in your query, Google will restrict your Google Groups results to newsgroup articles from certain groups or subareas. For example, [ sleep groups:misc.kids.moderated ] will return articles in the group misc.kids.moderated that contain the word "sleep" and [ sleep groups:misc.kids ] will return articles in the subarea misc.kids that contain the word "sleep."
id:
This is an undocumented alias for info:.
inanchor:
If you include inanchor: in your query, Google will restrict the results to pages containing the query terms you specify in the anchor or links to the page. For example, [ restaurants inanchor:gourmet ] will return pages in which the anchor text on links to the pages contain the word "gourmet" and the page contains the word "restaurants."
info:
The query info:url will present some information about the corresponding web page. For instance, [ info:gothotel.com ] will show information about the national hotel directory GotHotel.com home page. Note: There must be no space between the info: and the web page url.

This functionality can also be obtained by typing the web page url directly into a Google search box.

insubject:
If you include insubject: in your query, Google will restrict articles in Google Groups to those that contain the terms you specify in the subject. For example, [ insubject:"falling asleep" ] will return Google Group articles that contain the phrase "falling asleep" in the subject.

Equivalent to intitle:.

intext:
The query intext:term restricts results to documents containing term in the text. For instance, [ Hamish Reid intext:pandemonia ] will return documents that mention the word "pandemonia" in the text, and mention the names "Hamish" and "Reid" anywhere in the document (text or not). Note: There must be no space between the intext: and the following word.

Putting intext: in front of every word in your query is equivalent to putting allintext: at the front of your query, e.g., [ intext:handsome intext:poets ] is the same as [ allintext: handsome poets ].

intitle:
The query intitle:term restricts results to documents containing term in the title. For instance, [ flu shot intitle:help ] will return documents that mention the word "help" in their titles, and mention the words "flu" and "shot" anywhere in the document (title or not). Note: There must be no space between the intitle: and the following word.

Putting intitle: in front of every word in your query is equivalent to putting allintitle: at the front of your query, e.g., [ allintitle: google search ].

inurl:
If you include inurl: in your query, Google will restrict the results to documents containing that word in the url. For instance, [ inurl:healthy eating ] will return documents that mention the words "healthy" in their url, and mention the word "eating" anywhere in the document (url or no). Note: There must be no space between the inurl: and the following word.

Putting inurl: in front of every word in your query is equivalent to putting allinurl: at the front of your query, e.g., [ inurl:healthy inurl:eating ] is the same as [ allinurl: healthy eating ].

In URLs, words are often run together. They need not be run together when you're using inurl:.

link:
The query link:URL shows pages that point to that URL. For example, to find pages that point to Google Guide's home page, enter:

link:www.googleguide.com ]

Find links to the Google home page not on Google's own site.

link:www.google.com -site:google.com ]

location:
If you include location: in your query on Google News, only articles from the location you specify will be returned. For example, [ queen location:uk ] will show articles that match the term "queen" from sites in the United Kingdom.
movie:
If you include movie: in your query, Google will find movie-related information. For examples, see Google's Blog.
msgid:
If you include msgid: in your query, Google will restrict your Google Groups results to a newsgroup article with the specified message ID. For example, [ msgid:<hamishxyz-B270D1.09001126112003@news.supernews.com> ] will return the article whose message id is <hamishxyz-B270D1.09001126112003@news.supernews.com>.
phonebook:
If you start your query with phonebook:, Google shows all white page listings for the query terms you specify. For example, [ phonebook: Krispy Kreme Mountain View ] will show the phonebook listing of Krispy Kreme donut shops in Mountain View.
related:
The query related:URL will list web pages that are similar to the web page you specify. For instance, [ related:www.consumerreports.org ] will list web pages that are similar to the Consumer Reports home page. Note: Don't include a space between the related: and the web page url. You can also find similar pages from the Similar pages link on Google's main results page, and from the similar selector in the Page-Specific Search area of the Advanced Search page. If you expect to search frequently for similar pages, consider installing a GoogleScout browser button, which scouts for similar pages.
rphonebook:
If you start your query with rphonebook:, Google shows residential white page listings for the query terms you specify. For example, [ rphonebook: monty python Oakland ] will show the phonebook listing for Monty Python in Oakland.
safesearch:
If you include safesearch: in your query, Google will exclude adult-content. For example, [ safesearch:breasts ] will search for information on breasts without returning adult or pornographic sites.
site:
If you include site: in your query, Google will restrict your search results to the site or domain you specify. For example, [ admissions site:www.lse.ac.uk ] will show admissions information from London School of Economics' site and [ peace site:gov ] will find pages about peace within the .gov domain. You can specify a domain with or without a period, e.g., either as .gov or gov.

Note: Do not include a space between the "site:" and the domain.

You can use many of the search operators in conjunction with the basic search operators +, -, OR, " ." For example, to find information on Windows security from all sites except Microsoft.com, enter:

windows security -site:microsoft.com  ]

You can also restrict your results to as ite or domain through the domains selector on the Advanced Search page.

source:
If you include source: in your query, Google News will restrict your search to articles from the news source with the ID you specify. For example, [ election source:new_york_times ] will return with the word "election" that appear in the New York Times.

To find a news source ID, enter a query that includes a term and the name of the publication you're seeking. You can also specify the publication name in the "news source" field in the Advanced News Search form. You'll find the news source ID in the query box, following the source: search operator. For example, if the search box contains [ peace source:ha_aretz ], then the news source ID is ha_aretz. This query will only return articles that include the word "peace" from the Israeli newspaper Ha'aretz.

stocks:
If you start your query with stocks:, Google will interpret the rest of the query terms as stock ticker symbols, and will link to a page showing stock information for the symbols you specify. For instance, [ stocks:brcm brcd ] will show information about Broadcom Corporation and Brocade Communications System. Note: Specify ticker symbols not company names. If you enter an invalid ticker symbol, you'll be told so and taken to a page where you can look up a valid ticker symbol. You can also obtain stock information by entering one or more NYSE, NASDAQ, AMEX, or mutual fund ticker symbols in Google's query box, e.g., [ brcm brcd ] and then clicking on the "Show stock quotes" link that appears near the top of the results page.
store:
If you include store: in your query, Froogle will restrict your search to the store ID you specify. For example, [ polo shirt store:llbean ] will return listings that match the terms "polo" and "shirt" from the store L. L. Bean.

To find a store ID, enter the name of the store and click on the link "See all results from store." You'll find the store ID in the query box, after the store: search operator.

If you include weather in your query, Google will include weather for the location you specify. Since weather is not an advanced operator, there is no need to include a colon after the word. For example, [ weather Sunnyvale CA ] will return the weather for Sunnyvale, California and [ weather 94041 ] will return the weather for the city containing the zip code 94041, which is Mountain View, California.

The following table lists the search operators that work with each Google search service.

The Google Guide Advanced Operator Quick Reference (www.googleguide.com/advanced_operators_reference.html) provides a nice summary of the search operators grouped by type. It includes search operators not yet documented by Google, e.g., allinanchor:, allintext:, author:, ext:, group:, id:, insubject:, intext:, intitle:, location:, phonebook:, source:, and store:. Be forewarned that Google may change how undocumented operators work or eliminate them completely.

Using More than One Search Operator

You may use many of the basic operators and search operators with each other. However, there are some that must be used by themselves and others that you should be careful about using together.
