• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung si quyen vang. nguoi muong hoa mon ) OR ( nhung gi luan van. nuoi dong hoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung si quyen vang. nguoi muong hoa mon ) or ( nhung gi luan van. nuoi dong hoc mo ))*.
