MetaWiki

MetaWiki is a search engine that allows to search the page titles of several listed wikis. It was created by Sunir Shah.

Initially, the Wikipedia was one of the listed wikis, but it has been removed in November 2001, mostly because it has been failing to list for over two months. Also, it has a low overlap with other wikis, and there hasn't been much demand to create InterWiki links.
