In the era of hypertext and the World Wide Web,
Internet users can now search for information by clicking on text that
moves the user from one Internet site to another. Search services on the
Internet have been built to further aid users in their search for
information. Not all search services look for and collect information from
the Internet in the same manner. One search service, for example, may
allow full text searching of Web pages while another only allows the
search of abstracts of Web sites--titles, headings, subheadings, and the
first 20 lines.
A search service creates its own database of web addresses with the help of a program called a "worm" (also known as a robot) that follows links and retrieves hypertext documents, categorizing and updating information in the database. Search services can provide results fairly quickly because a search request queries the database instead of the entire World Wide Web. The frequency with which a "worm" updates a database varies with the search service, as does the extent of the Web it covers. Search services also differ in their search strategies. Some "worms" only search the titles of pages to compile a database, while others look at the entire text of a hypertext document.
