Veronica is to Gopher what Archie is to anonymous FTP. Veronica keeps a collection of all knows/registered Gopher menus. People can then search the database to gather a collection of menu items pertaining to (hopefully) a specific domain.
Those menu items are automatically put into a gopher-like menu.
Unlike indexed searches, Veronica is able to handle logical operations such as and, or, and not.
cold and whitewould only return menu items which contained the two words cold and white.
