The file search program Archie was implemented on the Internet via a network of so-called Archie servers. Each Archie server fetched all current tables of contents of the public file areas in a certain geographical area from the anonymous FTP servers
at regular intervals. The Archie servers also synchronized these lists with each other so that all Archie servers had the same current file directories
at all times.
The Archie servers created two databases: "Internet Archives Database" and "Software Description Database". The former contained a listing of all file names and could be searched using the Archie "find" command. The second database, which contained a sort of short description of features, could be accessed with the "whatis" command. The Archie search engine was discontinued.
