• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu xanh) OR (chieu sach)) - nhanh lang duong truong dong ((van than) or (van thanh)) cap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - nhanh lang duong truong dong ((van than) OR (van thanh)) cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - nhanh lang duong truong dong ((van than) or (van thanh)) cap".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sach)) - nhanh lang duong truong dong ((van than) or (van thanh)) cap*.
