Something I never knew before just today was that you can modify a search to exclude certain things. Example is I have a standing search for "1970 Camaro Used" in the parts section. Lately there have been many generic auto related tin signs that have shown up filling up the first couple of pages of the results. By adding a "-signs" to the search these are then removed from the results. Maybe most of you knew this, but for those that didn't it helps cut through the crap.
