Qwika is a search engine (like Google, for example), but for wikis.

It searches in all language editions of Wikipedia and in some of the various Wikia wikis (no longer including the Spanking Art wiki). It aims to include all sizeable wikis on the Internet, but currently indexes 1158 wikis in total - far fewer than exist in wikiindex.org's list of wikis.
