• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (doc hieu)) xanh - thanh trung ((hua khong) OR (cua khong)) cong manh toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) or (doc hieu)) xanh - thanh trung ((hua khong) OR (cua khong)) cong manh toan cao".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) or (doc hieu)) xanh - thanh trung ((hua khong) OR (cua khong)) cong manh toan cao*.
