• Performing a fuzzy search may retrieve terms with similar spellings: theo ((chieu sach) OR (chieu sang)) - canh tranh ((cua truong) or (xuan truong)) cong san tran van~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sach) OR (chieu sang)) - canh tranh ((cua truong) OR (xuan truong)) cong san tran van*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sach) OR (chieu sang)) - canh tranh ((cua truong) or (xuan truong)) cong san tran van*".
