• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - ban hang va hang cong dan ((((chan cau) OR (nhanh cau))) OR (phan cau))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - ban hang va hang cong dan ((((chan cau) OR (nhanh cau))) or (phan cau))*".
