• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu quang - canh tranh cua nhung cong san ((((toan cau) OR (toan ban))) OR (toan tap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu quang - canh tranh cua nhung cong san ((((toan cau) OR (toan ban))) or (toan tap))*".
