• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach hoc tap, nghien cuu mon hoc nganh khong ((hoc xa) OR (hoc ma)) hoi cu nhan van".
• Adding a wildcard symbol may retrieve word variants: su sach hoc tap, nghien cuu mon hoc nganh khong ((hoc xa) OR (hoc ma)) hoi cu nhan van*.
