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