Definition: search

(1) To look for specific data in a file or an occurrence of text in a file. A search implies either scanning content sequentially or using algorithms to compare multiple indexes to find a match. A search on the Web yields a list of Web pages that contain all the words in the search criteria (see SERP). Contrast with a "direct lookup," whereby a single index is used to keep track of data. See search engine, desktop search, Boolean search and query.

(2) The field of search engine technologies. See search engine.
