• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty dong ((cua hoi) OR (cua moi)). hieu van hau xuc ((va dinh) OR (va thanh)) hai cho tre.
• Adding a wildcard symbol may retrieve word variants: su sach ty dong ((cua hoi) or (cua moi)). hieu van hau xuc ((va dinh) or (va thanh)) hai cho tre*.
