• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang van hoe. hieu va cac tuc van doanh dao ((cua tu) OR (((cua cau) OR (cua chu))))~.
• Adding a wildcard symbol may retrieve word variants: te sach ky lang van hoe. hieu va cac tuc van doanh dao ((cua tu) or (((cua cau) or (cua chu))))*.
