Nobody wants to spend time scrolling through thousands of search results to find the page that contains the information they're looking for. In fact, few people bother looking beyond the first page of 10 results, choosing instead to recraft their search phrase and try again. But with the help of a few search operators, you can increase substantially the chances that you'll find what you're looking for on your first search try. (Note: not all of these work in every search engine.)
Restating the Obvious Operators
I'll wager you know all about using the plus sign (+) to search for two terms appearing together, the minus sign (-) to find pages that contain one term but not another, the asterisk (*) wildcard to search for a term along with any other word, and quotes ("blah de blah") to find an exact phrase. Here's another search character you might find handy: Place a tilde (~) directly in front of your search term to find pages with words similar to the term in question. So searching ~inexpensive laptop will return pages that have the term "cheap laptop," "affordable laptop," and "low-cost laptop" as well.
Many of my favorite Web sites have terrible site-search boxes. I usually have a much better chance of finding what I'm looking for on the site by going to Google or another search engine, and entering my search term along with site:www.thesitename.com (or .org, .edu, etc.) Here are some of my other favorite search limiters:
define:word to return a definition;
link:url to find pages that contain a link to a specific site or page;
inurl:searchterm (or allinurl:searchterm) to retrieve pages whose URL contains a specific word or phrase;
intitle:searchterm (or allintitle:searchterm the find pages with the word or phrase in their title; and,
info:url (or id:url) to get information about the page.
