• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky tang ma hoi. ((hieu ve) OR (hieu van)) cam tuc va ((thanh vi) OR (thanh ve)) hoa viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky tang ma hoi. ((hieu ve) OR (hieu van)) cam tuc va ((thanh vi) or (thanh ve)) hoa viet*".
