• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (doi chieu)) xanh - hanh truong cua ((ban cong) OR (van cong)) vang toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (doi chieu)) xanh - hanh truong cua ((ban cong) OR (van cong)) vang toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (doi chieu)) xanh - hanh truong cua ((ban cong) OR (van cong)) vang toan cau*.
