• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y van xay hoi. hieu ((((va tham) OR (va cham))) OR (va thanh)) thuc va danh dai cuu tre.
• Adding a wildcard symbol may retrieve word variants: su sach y van xay hoi. hieu ((((va tham) or (va cham))) or (va thanh)) thuc va danh dai cuu tre*.
