• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty sang ((lai hoi) or (xa hoi)). hieu va ((cac xuc) OR (cam xuc)) va thanh nhan cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty sang ((lai hoi) OR (xa hoi)). hieu va ((cac xuc) OR (cam xuc)) va thanh nhan cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty sang ((lai hoi) or (xa hoi)). hieu va ((cac xuc) OR (cam xuc)) va thanh nhan cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ty sang ((lai hoi) or (xa hoi)). hieu va ((cac xuc) OR (cam xuc)) va thanh nhan cua tre*.
