• If you are trying to use Boolean operators, they must be ALL CAPS: (( toc sach nha so giai phan thuong tin ) OR ( toc sach cap me gian lang thuong tin ))~.
• Adding a wildcard symbol may retrieve word variants: (( toc sach nha so giai phan thuong tin ) or ( toc sach cap me gian lang thuong tin ))*.
