• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sach - hanh trang cua nhung cong tan ((((nhuan ban) OR (quan tai))) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: hoc chieu sach - hanh trang cua nhung cong tan ((((nhuan ban) or (quan tai))) or (toan ban))*.
