Search Engine :
Computer program that searches documents, especially on the World Wide Web, for a specified word or words and provides a list of documents in which we are found
Web sites or software that search the Internet for documents that contain a key word, phrase, or subject that is specified by the user to the search engine. Each engine has its own method of searching for information.
A program that searches documents for specified keywords and returns a list of the documents where the keywords were found. Although search engine is really a general class of programs, the term is often used to specifically describe systems like Google, Alta Vista and Excite that enable users to search for documents on the World Wide Web
Typically, a search engine works by sending of the spider to fetch as many documents as possible. Another program, called an indexer, then reads these documents and creates an index based on the words contained in each document. Each search engine uses a proprietary algorithm to create its indices such that, ideally, only meaningful results are returned for each query.

Importance of search engine :
There's no denying the importance of search engines, but what a search engine actually is or does may remain a bit of a mystery. In simplest terms, a search engine is any software program that searches for sites based on the words users have keyed in, that have to do with the subject of their interest. Search engines are the work horses of the world wide web, returning billions of responses to billions of queries every day, with the major search engines being Google, Yahoo, Bing and Ask.
To the individual in business, potential customer's queries via search engines can mean great success, depending on how the business is positioned and how easily its products, websites, online ads, social media presence and blogs can be discovered.
