Okay. Newest frustration. Yesterday, you could do a search for "regulator +(victor, concoa)" and you would get a list of all items that had both "regulator" and "Victor" OR "Concoa" (or both) in the title. Today, the plus sign screws it up, and you get no results. Which means I have to go through all my saved searches and remove the "+" from them. I don't know why. Fortunately, the fix is simple - just remove the "+" before all parenthesis, and the searches work fine. Still, obnoxious.
I originally used the "+" to all saved searches because I'd seem some write-ups on the new search rules that included it.
