Those options in the search function just give you the chance to decide on what level you will look for a certain file i think. So whenever u search i think it's best to set it to global servers.
It doesn't really matter where or from what server the found files are from just click 'em and they will download (sooner or later). As long as you're on a bigger trustable server that is.
And please, anyone, correct me if i fucked up something here trying to explain
