• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky ((nang xa) OR (nang cao)) hoi. hieu ve cam xuc ((va danh) OR (van hanh)) vi va triet.
• Adding a wildcard symbol may retrieve word variants: tu sai ky ((nang xa) or (nang cao)) hoi. hieu ve cam xuc ((va danh) or (van hanh)) vi va triet*.
