• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) OR (ho chieu)) xanh - ((hanh tang) or (anh tang)) cua thong luong manh toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) OR (ho chieu)) xanh - ((hanh tang) or (anh tang)) cua thong luong manh toan tap*.
