• Performing a fuzzy search may retrieve terms with similar spellings: ho chiet tach - ((thanh truong) or (thanh cong)) hua khong ((cong thanh) OR (dong thanh)) toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chiet tach - ((thanh truong) OR (thanh cong)) hua khong ((cong thanh) OR (dong thanh)) toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chiet tach - ((thanh truong) or (thanh cong)) hua khong ((cong thanh) OR (dong thanh)) toan ban*".
