• If you are trying to use Boolean operators, they must be ALL CAPS: bo sach thu hang van hoe. hieu vu kham duc va thanh ban ((((cua tre) OR (cua te))) OR (cuu tre))~.
• Adding a wildcard symbol may retrieve word variants: bo sach thu hang van hoe. hieu vu kham duc va thanh ban ((((cua tre) or (cua te))) or (cuu tre))*.
