• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((mach hoc) OR (dich hoc)) tap, nghien cuu tin hoc danh hoa hoc xa hoi van phan van~".
• Adding a wildcard symbol may retrieve word variants: tu ((mach hoc) OR (dich hoc)) tap, nghien cuu tin hoc danh hoa hoc xa hoi van phan van*.
