cache:
The search engine keeps the text of the documents it indexes available in a backed-up format known as "cache." A cached version of a Web page can be retrieved if the original page is unavailable (for example, if the page's server is down). The cached page appears exactly as it looked when the search engine last indexed it and includes a message (at the top of the page) to indicate that it's a cached version of the page.
The query cache: followed by a URL shows the cached version of the page. For instance, cache:www.mla.org shows the cached version of the MLA's home page.
There should be no space between cache: and the URL in the query.
If you include other words in the query, they will be highlighted in the cached document. For instance, cache:www.mla.org press releases shows the cached content with the words "press" and "releases" highlighted.
info:
The query info: followed by a URL returns all information available for that URL. For instance, info:www.mla.org shows information about the MLA home page. There should be no space between info: and the URL.
site:
If you include site: followed by a domain name in your query, the results are restricted to the Web sites in the given domain. For instance, help site:mla.org finds pages about help within mla.org. There should be no space between site: and the domain.
link:
The query link: followed by a URL finds all pages that link to the given site. To do this, use the syntax link:sampledomain.com in the search box. (You may not specify other search terms when using this special query.)
For example, to find pages linked to Stanford University's main page, enter
allintitle:
If you start a query with allintitle:, the results are restricted to documents with all the query words in the document's HTML title. For example, allintitle: MLA search only returns documents that have both "MLA" and "search" in the HTML title.
intitle:
If you include intitle: followed by a word in your query, the search is restricted to documents containing that word in the HTML title. For example, intitle:MLA search returns documents that mention the word "MLA" in their HTML title and mention the word "search" anywhere in the document, either in the title or elsewhere.
There should be no space between 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. For example, intitle:MLA intitle:search is the same as allintitle: MLA search.
allinurl:
If you start a query with allinurl:, the search is restricted to results with all the query words in the URL. For example, allinurl: MLA search returns only documents that have both "MLA" and "search" in the URL.
Note that allinurl: ignores punctuation. Thus, allinurl: foo/bar restricts the results to pages with "foo" and "bar" in the URL but doesn't require that they be separated by a slash, be adjacent, or be in that order.
inurl:
If you include inurl: followed by a word in your query, the results are restricted to documents containing that word in the URL. For example, inurl:MLA search returns documents that mention the word "MLA" in their URL and mention the word "search" anywhere in the document, either in the URL or elsewhere.
There should be no space between inurl: and the following word.
Note that inurl: ignores punctuation. Thus, in the query inurl:foo/bar, the inurl: operator affects only "foo." The query 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. For example, inurl:MLA inurl:search is the same as allinurl: MLA search.
