• Performing a fuzzy search may retrieve terms with similar spellings: so sach ky dang ((hoai hoi) OR (hoa hoi)). hieu qua cam xuc ((ban thanh) or (va dan)) de cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky dang ((hoai hoi) OR (hoa hoi)). hieu qua cam xuc ((ban thanh) OR (va dan)) de cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky dang ((hoai hoi) OR (hoa hoi)). hieu qua cam xuc ((ban thanh) or (va dan)) de cua triet*".
