• If you are trying to use Boolean operators, they must be ALL CAPS: (( phuong thi xuan van. nuoi duong ho mon ) OR ( nhung thong que van. hoi trung quoc mont ))~.
• Adding a wildcard symbol may retrieve word variants: (( phuong thi xuan van. nuoi duong ho mon ) or ( nhung thong que van. hoi trung quoc mont ))*.
