• If you are trying to use Boolean operators, they must be ALL CAPS: ((toc sach) OR (thuoc sach)) hoc tap, nghien cuu mon hoc nganh khong hoc dai hoi dan nhan van~.
• Adding a wildcard symbol may retrieve word variants: ((toc sach) or (thuoc sach)) hoc tap, nghien cuu mon hoc nganh khong hoc dai hoi dan nhan van*.
