• The words AND, OR and NOT may confuse the search; try adding quotes: "theo cuu tinh - ((hanh trinh) or (hanh chinh)) cua nhung luong tai ((tuan ban) OR (luan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo cuu tinh - ((hanh trinh) or (hanh chinh)) cua nhung luong tai ((tuan ban) OR (luan ban))*.
