• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chi xanh) OR (chi danh)) - ((danh trung) OR (tdanh trung)) cua nong cong van luan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chi xanh) OR (chi danh)) - ((danh trung) or (tdanh trung)) cua nong cong van luan ban*".
