• Performing a fuzzy search may retrieve terms with similar spellings: so sach ky nang ((((van hoi) OR (van hoc))) or (van hoa)). hieu va cac xuc va hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky nang ((((van hoi) OR (van hoc))) OR (van hoa)). hieu va cac xuc va hanh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky nang ((((van hoi) OR (van hoc))) or (van hoa)). hieu va cac xuc va hanh vi cua triet*".
