• If you are trying to use Boolean operators, they must be ALL CAPS: (( phung tri quan quang. boi duong nguoc mo ) OR ( nhung thoi quen quang. nuoi ong hoc mon ))~.
• Adding a wildcard symbol may retrieve word variants: (( phung tri quan quang. boi duong nguoc mo ) or ( nhung thoi quen quang. nuoi ong hoc mon ))*.
