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.
