• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chuc danh) OR (chua xang)) - nhanh lang ((van nhuong) OR (van chuong)) cong van tan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chuc danh) or (chua xang)) - nhanh lang ((van nhuong) OR (van chuong)) cong van tan tap".
