• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung thoi quan van. thoi quyen cua lap ) OR ( nhung thoi quen vang. thoi quen chua lanh ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung thoi quan van. thoi quyen cua lap ) or ( nhung thoi quen vang. thoi quen chua lanh ))*.
