• If you are trying to use Boolean operators, they must be ALL CAPS: chao chu xanh - canh ((tranh luan) OR (trinh luat)) hung ((cuong manh) OR (cuong danh)) toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chao chu xanh - canh ((tranh luan) or (trinh luat)) hung ((cuong manh) OR (cuong danh)) toan cau*".
