• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (so sach)) ty hang ((ca hoi) OR (cau hoi)). hieu qua cam duc va thanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ty hang ((ca hoi) OR (cau hoi)). hieu qua cam duc va thanh vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sach)) ty hang ((ca hoi) OR (cau hoi)). hieu qua cam duc va thanh vai cua te".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (so sach)) ty hang ((ca hoi) OR (cau hoi)). hieu qua cam duc va thanh vai cua te*.
