About Search Engines

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

• Each search engine uses software to compile a database of pages found on the publicly accessible Web.
• When you enter a search, the search engine scans its own database to match your terms against terms in the pages of its database.
• No humans are involved with this process.

So, each search engine searches the part of the Web it has collected--not the whole Web--and each search engine has a somewhat different database. NO search engine searches everything on the Web.
