That's because of Wikia decisions of making it the hard way.

I've repeated several times how this change would be so simple to accomplish, but no, Wikia has spent a lot of time mangling the core MediaWiki code to break it, and applying patches and more patches to this mess just to make a preference option to work, when the most easy way would have been to add a "fulltext" named hidden field in the Oasis skin search form!!

And search is still broken using opensearch and Special:Search/whatever!!
