• If you are trying to use Boolean operators, they must be ALL CAPS: ((mot chieu) OR (ho chieu)) xanh - thanh trung va hang hong hanh ((toan cao) OR (toan tap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (ho chieu)) xanh - thanh trung va hang hong hanh ((toan cao) OR (toan tap))*".
