• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho hieu) OR (hoi hieu)) lang - thanh thang ap dung cong ((dan than) OR (ban than)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho hieu) or (hoi hieu)) lang - thanh thang ap dung cong ((dan than) OR (ban than)) cau".
