• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung thoi que lang. nguoi duong khoa co ) OR ( nhung dai quyen vang. nuoi duong hoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung thoi que lang. nguoi duong khoa co ) or ( nhung dai quyen vang. nuoi duong hoc mo ))*.
