Martijn Koster Introduces ALIWEB (Archie Like Indexing for the Web). Is this the First Web Search Engine?

On November 30, 1993 Martijn Koster introduced ALIWEB, (Archie Like Indexing for the Web). Along with the World Wide Web Wanderer, this was a candidate for the first web search engine. It was demonstrated at the First International World-Wide Web Conference in May 1994.

"Aliweb allowed users to submit their webpages and add the page description with which they wanted them to be indexed. This empowered webmasters, who could define the terms that would lead users to their pages and also avoided setting bots (as the Wanderer) which used up bandwidth. Aliweb was not very successful as not many people submitted their sites."
