• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo hieu) OR (theo chieu)) lang - thanh trung cua bang cong dan ((phan cac) OR (phan dau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo hieu) or (theo chieu)) lang - thanh trung cua bang cong dan ((phan cac) OR (phan dau))~".
• Adding a wildcard symbol may retrieve word variants: ((theo hieu) or (theo chieu)) lang - thanh trung cua bang cong dan ((phan cac) OR (phan dau))*.
