• If you are trying to use Boolean operators, they must be ALL CAPS: (( hoc sach tranh nghiep du hoc ) OR ( su ((sach trach) OR (sat trach)) nghiep bang hoc ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( hoc sach tranh nghiep du hoc ) or ( su ((sach trach) OR (sat trach)) nghiep bang hoc ))~".
• Adding a wildcard symbol may retrieve word variants: (( hoc sach tranh nghiep du hoc ) or ( su ((sach trach) OR (sat trach)) nghiep bang hoc ))*.
