I have no idea how hard this would be to do but adding Boolean commands would be great.

I use the search A LOT and thank you for that but often I get the same posts by the same people
that are a mile long, have no price listed, and the items posted more than once on the list
IE trap gc on d2ehcl

to be able to say trap gc NOT Dyermaker for example would be nice or if there is a way to block certain threads from re appearing.
