• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung bai quen vang. nuoi duong thuoc bao ) OR ( nhung thoi quan lang. boi duong nguoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung bai quen vang. nuoi duong thuoc bao ) or ( nhung thoi quan lang. boi duong nguoc mo ))*.
