• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung vi quan va. hoi dang quoc mo ) OR ( nhung loi quan van. hai duong nguoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung vi quan va. hoi dang quoc mo ) or ( nhung loi quan van. hai duong nguoc mo ))*.
