Definition
A Search Engine is used to look through all of the information that is on the World Wide Web and find specific data. The results of the searches are most often returned in a lined list with the most relevant pages to the search at the top and least relevant at the bottom. Information returned may be a mix of images, web pages, and other types of files.

History
The first search engine that was well documented was named Archie and debuted in September 1990. Before 1993, the World Wide Web was entirely indexed (recorded) by hand. There was a list of web-servers edited by Tim Berners-Lee and hosted on the CERN web-server. The company Google retains a snapshot of the list from 1992, but as more web servers went online and the World Wide Web started to grow the central list could not keep up. The first search engine to use a crawler based algorithm was developed in 1994 and was titled Webcrawler. The new engine allowed users to search any word on any page hosted on the World Wide Web. This advancement in search algorithms led to the development of the major search engines of Yahoo and Google which refined the search abilities and still use them in some form today.
