• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu bach lam nghiep luan hoc ) OR ( te sach tham ((nghiep trung) OR (nghiep trong)) quoc )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu bach lam nghiep luan hoc ) or ( te sach tham ((nghiep trung) OR (nghiep trong)) quoc ))".
• Adding a wildcard symbol may retrieve word variants: (( thu bach lam nghiep luan hoc ) or ( te sach tham ((nghiep trung) OR (nghiep trong)) quoc ))*.
