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