| Uses a robot or
computer to search for words or topics on a certain website, or all
over the web. On the
Internet, a search engine is a coordinated set of programs that
includes: A spider (also called a "crawler" or a "bot") that goes to
every page or representative pages on every Web site that wants to
be searchable and reads it, using hypertext links on each page to
discover and read a site's other pages, a program that creates a
huge index (sometimes called a "catalog") from the pages that have
been read, and a program that receives your search request,
compares it to the entries in the index, and returns results to you. |
