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