• If you are trying to use Boolean operators, they must be ALL CAPS: (( (phung OR phong) thi quan va. nuoi duong ho mot ) OR ( nhung tren que van. hoc dung hoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( (phung or phong) thi quan va. nuoi duong ho mot ) or ( nhung tren que van. hoc dung hoc mo ))*.
