• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky sang ((tao hoi) OR (tao khoi)). hieu ve cam xuc ((va hanh) or (dia danh)) hai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky sang ((tao hoi) OR (tao khoi)). hieu ve cam xuc ((va hanh) OR (dia danh)) hai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky sang ((tao hoi) OR (tao khoi)). hieu ve cam xuc ((va hanh) or (dia danh)) hai cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ky sang ((tao hoi) OR (tao khoi)). hieu ve cam xuc ((va hanh) or (dia danh)) hai cua tre*.
