• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sach) OR (chinh sach)) - thanh trang van hang ((nong dan) OR (nong san)) toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sach) or (chinh sach)) - thanh trang van hang ((nong dan) OR (nong san)) toan cao".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sach) or (chinh sach)) - thanh trang van hang ((nong dan) OR (nong san)) toan cao*.
