• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu sach - ((thanh cuong) OR (thanh chuong)) dan nhung cong ((bang thanh) or (ban thanh)) san~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((thanh cuong) OR (thanh chuong)) dan nhung cong ((bang thanh) OR (ban thanh)) san.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((thanh cuong) OR (thanh chuong)) dan nhung cong ((bang thanh) or (ban thanh)) san".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - ((thanh cuong) OR (thanh chuong)) dan nhung cong ((bang thanh) or (ban thanh)) san*.
