Search Function in PM's does not work, or maybe it's just me?

Has anyone else noticed the above, If I want to say search through PM's for a conversation with a certain member or the title of our conversation the search results are always null I have tried many different combinations to get some sort of result but still, nothing, is there something I am missing?

Okay Thanks for checking that mate, I've played with it a bit more and I have been able to bring up search results but it seems searches have to be over a certain number of characters and are only on the title of a PM for example I couldn't search for a conversation with a specific user is that the case? It doesn't really bother me at all I just remember on the old forum it used to bring up user name or title.
