• If you are trying to use Boolean operators, they must be ALL CAPS: (( phong thi que van. nguoi vong hoc mon ) OR ( nhung thoi quan van. nguoi muong ho mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( phong thi que van. nguoi vong hoc mon ) or ( nhung thoi quan van. nguoi muong ho mo ))*.
