• The words AND, OR and NOT may confuse the search; try adding quotes: "theo dieu hanh - thanh trung cua ((nhung cong) or (dang cong)) van ((tuan ban) OR (tuan bang))~".
• Adding a wildcard symbol may retrieve word variants: theo dieu hanh - thanh trung cua ((nhung cong) or (dang cong)) van ((tuan ban) OR (tuan bang))*.
