Whats with the search function?

This has been happening quite a lot lately and I have noticed other people have been having the same problem. When you search the forum it just kicks up a blank screen. I have tried multiple times over the last few weeks to search and its only worked once for me. I hate asking questions that have been answered many times before, it just adds to the clutter on a forum. Any one know why its doing this?
