How do search engines operating on the Web work?
What will be an ideal response?
Search engines use automated software programs to survey the Web and find the information you want. These programs retrieve and analyze documents that match your search criteria, and the data collected from each Web page is then added to the search engine's database. When you enter a query at a search engine site, your input is checked against the search engine's index of all the Web pages it has analyzed. The best URLs are then returned to you.
