• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung tri quy van. nguoi muong hoc mo ) OR ( nhung tri luan vang. hai duong hoi mont ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung tri quy van. nguoi muong hoc mo ) or ( nhung tri luan vang. hai duong hoi mont ))*.
