• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hieu manh - ((thanh trung) OR (thanh cong)) thuat tuong cong ((van toan) OR (van tan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hieu manh - ((thanh trung) or (thanh cong)) thuat tuong cong ((van toan) OR (van tan)) cau*".
