• If you are trying to use Boolean operators, they must be ALL CAPS: thuat dan y nang ((((ma hoi) OR (mai hoi))) OR (ma hoa)). hieu ve cac duc anh hanh va cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat dan y nang ((((ma hoi) OR (mai hoi))) or (ma hoa)). hieu ve cac duc anh hanh va cua tre*".
