• Performing a fuzzy search may retrieve terms with similar spellings: ((su dai) OR (si dai)) ky nang ((ma hoa) or (mai hoi)). hieu van cam xuc van hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su dai) OR (si dai)) ky nang ((ma hoa) OR (mai hoi)). hieu van cam xuc van hanh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su dai) OR (si dai)) ky nang ((ma hoa) or (mai hoi)). hieu van cam xuc van hanh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: ((su dai) OR (si dai)) ky nang ((ma hoa) or (mai hoi)). hieu van cam xuc van hanh vi cua triet*.
