• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - thanh chuong hieu chung cong dan ((((khan ap) OR (han ap))) OR (khan dam))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - thanh chuong hieu chung cong dan ((((khan ap) OR (han ap))) or (khan dam))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - thanh chuong hieu chung cong dan ((((khan ap) OR (han ap))) or (khan dam))*.
