I have searched for files that are over 100mb and when i do i get about 500 95kb files that have nothing to do with this. It's just a load of spam. I wonder if a file size filter would show more results of the file you actually want rather that just fill up your results with spam crap. Unless limewire doesn't want this option in it's program in support of spam.

I don't know how the searches work exactly but it would seem that spam floods the network.
