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