Search EnginesDefinition Tool for finding information, especially on the Internet or World Wide Web.

Most consist of three parts: at least one program, called a spider, crawler, or bot, which “crawls” through the Internet gathering information; a database, which stores the gathered information; a search tool, with which users search through the database by typing in keywords describing the information desired.
