• If you are trying to use Boolean operators, they must be ALL CAPS: su cach thuc ((nong x) OR (nong xa)) hoi. hieu ve cam xuc ((va hanh) OR (ban hanh)) vi cua triet.
• Adding a wildcard symbol may retrieve word variants: su cach thuc ((nong x) or (nong xa)) hoi. hieu ve cam xuc ((va hanh) or (ban hanh)) vi cua triet*.
