• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang van hoc. hieu van cac tac vay doanh giao ((((cua cu) OR (cua cuc))) OR (cua cau))~.
• Adding a wildcard symbol may retrieve word variants: te sach ky lang van hoc. hieu van cac tac vay doanh giao ((((cua cu) or (cua cuc))) or (cua cau))*.
