• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y trong van hoi. hieu ve ((((cach de) OR (cac he))) OR (cac du)) thanh lan hai cua triet.
• Adding a wildcard symbol may retrieve word variants: su sach y trong van hoi. hieu ve ((((cach de) or (cac he))) or (cac du)) thanh lan hai cua triet*.
