I got a couple of these set up. One specifically for LV chips and one for all. Mine is

-(case, set, 11.5*, kit, vintage, 300+, book, bakelite, ebook, table, pieces, holdem, frame, AIR -TITE)

This seems to cut out all the items I dont want. I might be have a false positive or two but its worth it if I dont have to wade through the things I am not interested in.
