Please note that I opened this ticket to report NOT a problem with the prefixsearch, but a problem with Wikimedia's regular search results. Please see an example of an unsuccesful search in the image attached.

I think the completion suggester will be a nice tool to help users, but I don't see how that is similar to solving the problem I described here, which is basically a big malfunction in wikimedia's search engine. The search engine should work well, regardlessly of the existence of a completion suggester. I'm worried about this ticket being closed without further action on that.
