Web Crawler was the first search engine to provide full text search.

With Web Crawler, Brian generated a list of the Top 25 websites on March 15, 1994.
As the central list of web servers joining the Internet grew, and the World Wide Web became the interface of choice for accessing the Internet, the need for finding and organizing the distributed data files on FTP web servers grew.
Search engines began due to this need to more easily navigate the web servers and files on the Internet.
The first search engine was developed as a school project by Alan Emtage, a student at Mc Gill University in Montreal.
Back in 1990, Alan created Archie, an index (or archives) of computer files stored on anonymous FTP web sites in a given network of computers (“Archie” rather than “Archives” fit name length parameters – thus it became the name of the first search engine).
Rather, in 1993 the graphical Mosaic web browser improved upon Gopher’s primarily text-based interface.
About the same time, Matthew Gray developed Wandex, the first search engine in the form that we know search engines today.
Only a month later on April 20, 1994, Brian announced the release of Web Crawler live on the web with a database of 4000 websites.
On June 11, 1994, Brian posted to the Usenet group comp.infosystems.announce that the Web Crawler Index was available for searching.
While both web directories and search engines gained popularity in the 1990s, search engines developed a life of their own becoming the preferred method of Internet search.Tags: Adult Dating, affair dating, sex dating
