• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (hieu lang)) - thanh dung cua dung cong ban ((thanh cau) OR (nhanh cau))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (hieu lang)) - thanh dung cua dung cong ban ((thanh cau) OR (nhanh cau))*".
