• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh ((huong cua) OR (tang luan)) nhung tuong van ((toan cau) OR (toan ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh ((huong cua) or (tang luan)) nhung tuong van ((toan cau) OR (toan ban))*".
