• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) OR (hien nhanh)) - canh tranh cua nhung huong ((van toan) or (van thanh)) cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) OR (hien nhanh)) - canh tranh cua nhung huong ((van toan) or (van thanh)) cau*.
