I suggest not using the search function at all. It sucks up an enormous amount of CPU cycles and it may be a factor of your host kicking you off for being a resource hogger.
Good idea, When my UBB was up, I didn't know one person who used the search. So I turned it off so I could add more cosmetics at the top of the forum and they wouldn't go on two lines.
Thanks guys, after all its not very useful as you just mentioned. Maybe it is useful for a UBB dedicated to informations like this UBB (search is VERY useful here) not it is not in my UBB fortunately.
