What is Search Engine

A search engine is a software system that is designed to carry out web searches, which means to search the World Wide Web (www) in a systematic way for particular information specified in a textual web search query.

A search engine is a web based tool\website through which users can search internet content. To do this, users enter the desired search term into the search field. The search engine then looks through its index for relevant websites and displays them in the form of a list.
