A search engine is an information retrieval system designed to help find information stored on a computer system.
The search results are usually presented in a list and are commonly called hits.
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.
Search engines provide an interface to a group of items that enables users to specify criteria about an item of interest and have the engine find the matching items.
