Our search engine supports several advanced operators, which are query words that have special meaning. Typically these operators modify the search in some way, or even tell us to do a totally different type of search. For instance, "link:" is a special operator, and the query [link:www.att.net] doesn't do a normal search but instead finds all web pages that have links to www.att.net.

Several of the more common operators use punctuation instead of words, or do not require a colon. Among these operators are OR, "" (the quote operator), - (the minus operator), and + (the plus operator). More information on these types of operators is available on the Search Help page.

Many of these special operators are accessible from the Advanced Search page, but some are not. Below is a list of all the special operators our search supports.

Alternate Query Types

cache:

The query [cache:] will show the version of the web page that is in our cache. For instance, [ cache:www.att.net] will show the most recent cached version of the AT&T Worldnet Service homepage. Note there can be no space between the "cache:" and the web page url.

If you include other words in the query, you will see the words highlighted within the cached document. For instance, [cache:www.att.net web] will show the cached content with the word "web" highlighted.

This functionality is also accessible by clicking on the "Cached" links in our search results page.

link:

The query [link:] will list web pages that have links to the specified web page. For instance, [link:www.att.net] will list web pages that have links pointing to the AT&T Worldnet Service homepage. Note there can be no space between the "link:" and the web page url.

related:

The query [related:] will list web pages that are "similar" to a specified web page. For instance, [related:www.att.net] will list web pages that are similar to the AT&T Worldnet Service homepage. Note there can be no space between the "related:" and the web page url.

info:

The query [info:] will present some information that our search engine has about that web page. For instance, [info:www.att.net] will show information about the AT&T Worldnet Service homepage. Note there can be no space between the "info:" and the web page url.

This functionality is also accessible by typing the web page url directly into our search box.

Query Modifiers

site:

If you include [site:] in your query, our search engine will restrict the results to those websites in the given domain. For instance, [help site:www.att.net] will find pages about help within www.att.net. [help site:net] will find pages about help within .net urls. Note there can be no space between the "site:" and the domain.

allintitle:

If you start a query with [allintitle:], our search will restrict the results to those with all of the query words in the title. For instance, [allintitle:welcome worldnet] will return only documents that have "welcome" and "worldnet" in the title.

intitle:

If you include [intitle:] in your query, our search will restrict the results to documents containing that word in the title. For instance, [intitle:welcome worldnet] will return documents that mention the word "welcome" in their title, and mention the word "worldnet" anywhere in the document (title or no). Note there can 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: [intitle:welcome intitle:worldnet] is the same as [allintitle: welcome worldnet].

allinurl:

If you start a query with [allinurl:], our search will restrict the results to those with all of the query words in the url. For instance, [allinurl: google search] will return only documents that have both "google" and "search" in the url.

Note that [allinurl:] works on words, not url components. In particular, it ignores punctuation. Thus, [allinurl: foo/bar] will restrict the results to page with the words "foo" and "bar" in the url, but won't require that they be separated by a slash within that url, that they be adjacent, or that they be in that particular word order. There is currently no way to enforce these constraints.

inurl:

If you include [inurl:] in your query, our search will restrict the results to documents containing that word in the url. For instance, [inurl:google search] will return documents that mention the word "google" in their url, and mention the word "search" anywhere in the document (url or no). Note there can be no space between the "inurl:" and the following word.

Note that [inurl:] works on words, not url components. In particular, it ignores punctuation. Thus, in the query [google inurl:foo/bar], the "inurl:" operator will affect only the word "foo", which is the single word following the inurl: operator, and will not affect the word "bar". The query [google inurl:foo inurl:bar] can be used to require both "foo" and "bar" to be in the url.

Putting "inurl:" in front of every word in your query is equivalent to putting "allinurl:" at the front of your query: [inurl:google inurl:search] is the same as [allinurl: google search].
