There is add _ to yout keyword filter

And BTW if you had read the thread properly you would see that this is about three seperate filters

1. A filesize filter with ranges
2. An IP filter built in to Limewire
and 3. A HASH filter

They would find themselves in heaps of trouble coming up with many bad files if ALL of them were implemented into Limewire

And BTW the ability to search by exact phrase would also help as the bad results would not be triggered nearly as often
