• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach hoc tap, nghien cuu luong cuoc thanh cong hoc xa hoi ((cua luan) OR (cua luat)) van~".
• Adding a wildcard symbol may retrieve word variants: tu sach hoc tap, nghien cuu luong cuoc thanh cong hoc xa hoi ((cua luan) OR (cua luat)) van*.
