Intitle: at the beginning of a query word or phrase (intitle:"Three Blind Mice") restricts your search results to just the titles of Web pages.


Intext: does the opposite of intitle:, searching only the body text, ignoring titles, links, and so forth. Intext: is perfect when what you're searching for might commonly appear in URLs. If you're looking for the term HTML, for example, and you don't want to get results such as
Example: mysite



Link: lets you see which pages are linking to your Web page or to another page you're interested in. For example, try typing in
link: Hackingstore.blogspot.com



inurl: restricts results to sites whose URL contains the specified phrase

example: inurl:fox fire will find all sites containing the word fire in the text and fox in the URL


filetype, ext: restricts results to documents of the specified type

example: filetype:pdf fire will return PDFs containing the word fire, while filetype:xls fox will return Excel spreadsheets with the word fox
