• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu hoach xet nghiem su hoc ) OR ( ((tu sach) OR (te sach)) giao nghiep dai hoc )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu hoach xet nghiem su hoc ) or ( ((tu sach) OR (te sach)) giao nghiep dai hoc ))".
• Adding a wildcard symbol may retrieve word variants: (( thu hoach xet nghiem su hoc ) or ( ((tu sach) OR (te sach)) giao nghiep dai hoc ))*.
