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