• If you are trying to use Boolean operators, they must be ALL CAPS: ((thi chieu) OR (ho chieu)) xanh - ((hanh trang) OR (thanh trung)) cua dung cong van toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thi chieu) or (ho chieu)) xanh - ((hanh trang) OR (thanh trung)) cua dung cong van toan ban*".
