• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty sang ((ma hoi) OR (xa hoi)). hieu ve ((cac xuc) OR (cam xuc)) va hanh dai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty sang ((ma hoi) or (xa hoi)). hieu ve ((cac xuc) OR (cam xuc)) va hanh dai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ty sang ((ma hoi) or (xa hoi)). hieu ve ((cac xuc) OR (cam xuc)) va hanh dai cua tre*.
