• Performing a fuzzy search may retrieve terms with similar spellings: su cao tu tong ((x hoi) OR (xa hoi)). hieu ve cac xuc ((va hanh) or (ban hanh)) vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su cao tu tong ((x hoi) OR (xa hoi)). hieu ve cac xuc ((va hanh) OR (ban hanh)) vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su cao tu tong ((x hoi) OR (xa hoi)). hieu ve cac xuc ((va hanh) or (ban hanh)) vi cua triet".
• Adding a wildcard symbol may retrieve word variants: su cao tu tong ((x hoi) OR (xa hoi)). hieu ve cac xuc ((va hanh) or (ban hanh)) vi cua triet*.
