About
Search Engines
So
what are 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 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. Keep in mind
that the software finds the web page and puts information it
collects into its database. A person does not look at or view
it.
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.
