• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung thi que van. bui chuong doi mo ) OR ( nhung thoi luan van. con duong nguoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung thi que van. bui chuong doi mo ) or ( nhung thoi luan van. con duong nguoc mo ))*.
