PDNS Recursor 3.3, downloaded and compiled from tar.gz source.
My questions are:
- why do i get much less result compared to Google DNS ?
- which configuration item of recursor.conf should i change to get
similar result of google DNS?
It seems that google resolves the CNAME, but powerdns and bind (which I
used) do not resolve the CNAME for 'any'.

Thus, in you lua script, just make another lookup for the domain in the
CNAME record.
