• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) OR (so sanh)) hoc tap, nghien cuu trong hoc nganh khoa hoc xa hoi cac nhan van~".
• Adding a wildcard symbol may retrieve word variants: ((so sach) OR (so sanh)) hoc tap, nghien cuu trong hoc nganh khoa hoc xa hoi cac nhan van*.
