Search

A search engine is an information retrieval system designed to help find information stored on a computer system. Search engines help to minimize the time required to find information and the amount of information which must be consulted, akin to other techniques for managing information overload. The most popular form of a search engine is a Web search engine which searches for information on the public World Wide Web. Other kinds of search engines include enterprise search engines, which search on intranets, personal search engines, and mobile search engines.
