Have a look at http://magnusmanske.de/wordpress/?p=108 Magnus Manske wrote a js-code that shows you if there is a wikidata-article and added this info to Spezial:Search. Another positive feature is that it shows the label which is added in wikidata. For example it tolds that Ågestasjön is a lake in Sweden. I added the code to my global.js page and it is really helpful. And there is an other point. I have looked into the help pages of the new Cirrus search and the old search and i found lots of possibilities i didn´t knew. I think you should try and find ways that the search-box gives more information to its users what is possible. For example, Spezial:Search could be used for searching files on commons. My guess is, that less than 1 percent of the users knew that. If commons will be integrated into Wikidata (commons:Structured data), search will be getting even more central to users. For example, below full text search in the box there could be integrated a search field for commons search (and wikidata search, called: "media and data search ...").
