The correct option is A World Wide Web Worm
The World-Wide Web Worm (WWWW) is the first search engine for the World-Wide Web, though it was not released until March 1994, by which time a number of other search engines had been made publicly available.
It was developed in September 1993 by Oliver McBryan at the University of Colorado. The worm created a database of 300,000 multimedia objects which could be obtained or searched for keywords via the WWW. In contrast to present-day search engines, the WWWW featured support for Perl regular expressions.
