• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu nganh - thanh trung cua dong cong ban ((((than cau) OR (phan cau))) OR (than cap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc hieu nganh - thanh trung cua dong cong ban ((((than cau) OR (phan cau))) or (than cap))*".
