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