• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky nang ((((ma hoi) OR (mai hoi))) or (xa hoi)). hieu van cac xuc va hanh dai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang ((((ma hoi) OR (mai hoi))) OR (xa hoi)). hieu van cac xuc va hanh dai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang ((((ma hoi) OR (mai hoi))) or (xa hoi)). hieu van cac xuc va hanh dai cua te*".
