• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chinh sach) or (chieu xanh)) - nhanh quang cua tong cong vang ((tan cau) OR (toan cau))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chinh sach) or (chieu xanh)) - nhanh quang cua tong cong vang ((tan cau) OR (toan cau))*.
