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