That's not what NOERROR means.  NOERROR simply means RCODE=0 and says
nothing about whether there are records in the response or not.

The situation of RCODE=0 and no records in the answer section is
sometimes referred to as NOERROR/NODATA (e.g., RFC6840 section 4.3) or
simply NODATA (RFC2308 section 2.2).
