Google has been my number one resource for information ever since Altavista decided to change their search service to allinone web portal. Here are few of my favourite tweaks I use to get more out from Google Search.
Define: gives you description of word or phrase. I.e. define:Finland or define:semantic.
Intitle: at the beginning of a query word or phrase (intitle:”Jukka-Pekka Keisala”) 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.
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:http://www.jpkeisala.com.
Site: which restricts results to top-level domains with intitle: to find certain types of pages. For example, get scholarly pages about Mark Twain by searching for intitle:”Mark Twain”site:edu.
Daterange: (start date?end date). You can restrict your searches to pages that were indexed within a certain time period.
Google has a fairly complete list of its syntax elements at www.google.com/help/operators.html.
Other intresting google tools like Google Alert (www.googlealert.com) monitors your search terms and e-mails you information about new additions to Google’s Web index. Intresting but I dont really use email anymore since spam has taken over pretty much my mail. But more intresting is Google on the telephone? Yup. Check out Google Voice Search
