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