• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chua xang) OR (chuc nang)) - thanh trung ((cua nong) OR (cua dong)) cong san than cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chua xang) or (chuc nang)) - thanh trung ((cua nong) OR (cua dong)) cong san than cau*".
