The new search format

Are there bugs in the new GB search platform. I have regular problems with it and find it much less user friendly than the old format. example: I just tried to search completed auctions of .32 caliber black powder rifles, title only, blackpowder rifles only, and keep getting 32,000 plus hits, apparently giving me everything with .32 in the title? I can't figure out what if anything I am doing wrong.
