administrators?

I was wondering what the possiblity of changing the search characters to 3 instead of 4? I can not even count the times I have needed to do a search and there is only 3 letters (ex 416/425/440/prm/rpm) But instead found myself going to a like topic and searching through countless threads. Just a thought and I am sure some of the people on here will agree that this would make the site more user friendly. :p
Ben the C-dale site looks good. Better slow the process before I go and get rid of the ex for one:devil

There is something you type in I think it is* but I'm not sure. it will work with 3 letters or less.
