Ah, I think I misunderstood.
Wikiwix is integrated as a search engine in the French Special:Search function. If you use the Wikiwix search option, it redirects you to an external site (http://fr.wikiwix.com/index.php?title=Sp%C3%A9cial%3ARecherche&redirs=0&... as an example), and this site returns results both for Wikipedia pages and for other external sites. In the example above, the external sites are for an Android phone and a Belgian escort service.
