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