• If you are trying to use Boolean operators, they must be ALL CAPS: (( su ((sach thi) OR (sach thieu)) nghiem du hoc ) OR ( vu sach thuat nghiep cua hoc ))~.
• Adding a wildcard symbol may retrieve word variants: (( su ((sach thi) or (sach thieu)) nghiem du hoc ) or ( vu sach thuat nghiep cua hoc ))*.
