• Performing a fuzzy search may retrieve terms with similar spellings: su cac tru nang x hoi. ((hieu ve) OR (hieu van)) cam xuc ((va hanh) or (ban hanh)) vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su cac tru nang x hoi. ((hieu ve) OR (hieu van)) cam xuc ((va hanh) OR (ban hanh)) vi cua triet.
