I know, I hate it too. We have to disable searching until the MySQL server can stabalize. HomeLAN and I are working on a fix, but part of that fix requires us logging things, which has a significant performance hit. To counter act that, I will be disabling searching. Currently, this only affects guests. Once you login, you will be able to search. I think that should be enough of an edge, but in the event it isn't, I will disable searching entirely until a permanent fix can be found.
[Edit : Yeah, so not that many guests search. User searching is going offline for a bit]
