About Search Engines

Search engines are handy tools that help you find what you want on the Web.

Each search engine uses software (called spiders or robots) to roam the Web and compile a database of pages it finds. When you enter a search, the search engine scans its own database to match your terms against terms found on the pages it has visited.

Searching for the same word(s) in different search engines will give you different results, depending on the web pages that particular search engine has happened to index in its database.
