• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y nang) OR (van nang)) x ho. hieu nghe nam thuc xa danh dai ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y nang) or (van nang)) x ho. hieu nghe nam thuc xa danh dai ((cua tre) OR (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y nang) or (van nang)) x ho. hieu nghe nam thuc xa danh dai ((cua tre) OR (cuu tre))*.
