• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sang)) - thanh trung cua tuong duong manh ((toan tap) OR (toan cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sang)) - thanh trung cua tuong duong manh ((toan tap) or (toan cao))*".
