• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) y lang van hoi. ((hieu ve) OR (hieu qua)) cam duc thang hanh mau va trien~.
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (su sach)) y lang van hoi. ((hieu ve) or (hieu qua)) cam duc thang hanh mau va trien*.
