• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoa thiet) OR (ho chieu)) tach - hanh manh cua tong cong dan ((than man) OR (tran manh))~.
• Adding a wildcard symbol may retrieve word variants: ((hoa thiet) or (ho chieu)) tach - hanh manh cua tong cong dan ((than man) or (tran manh))*.
