• Performing a fuzzy search may retrieve terms with similar spellings: ((su xac) or (su cac)) ky nang ((mai hoi) OR (lai hoi)). hieu ve cam xuc van hanh moi hoat viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su xac) OR (su cac)) ky nang ((mai hoi) OR (lai hoi)). hieu ve cam xuc van hanh moi hoat viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su xac) or (su cac)) ky nang ((mai hoi) OR (lai hoi)). hieu ve cam xuc van hanh moi hoat viet".
