Closed forums => no Search feature?

I’m trying to search for threads in Ordered, but I can’t. It keeps returning a “no matches - sorry” message. So unless you explicitly search for a post made by a user, it won’t work. (I was searching for something else, but I’m pretty sure ‘Bush’ is the most frequent word in that particular forum, yet it can’t find any matches for that as well. So try for yourself and see.)

Something is up or is that how vB is designed?
