• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (thi chien)) xanh - thanh tung ((chua duong) OR (chua dong)) cong san than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (thi chien)) xanh - thanh tung ((chua duong) OR (chua dong)) cong san than cau".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (thi chien)) xanh - thanh tung ((chua duong) OR (chua dong)) cong san than cau*.
