It's a pity we can't control the bots better.

FWIW: here an old workaround I'm using for Google (already for at least 10-15 years):

https://www.google.com/search?sitesearch=www.perlmonks.org&q=%22Node%20Type:%20perlquestion%22%20inurl:node_id%20-displaytype%20-index.pl

NB: by design it will only find complete threads.

https://www.google.com/search?q=warnings+site%3Aperlmonks.org

Probably depends on robots.txt settings and subsequent indexing.

Update

On a side note, my mobile Chrome can't use the site anymore when logged out.

So the choice of domain in the site-search has direct consequences.

IIRC, something was added to specify that perlmonks.org or www.perlmonks.org is the official domain, so no surprise you get better result from that one.

Yes, see the corresponding robots.txts

Like

• https://perlmonks.com/robots.txt

  # Please only spider https://www.perlmonks.org not https://perlmonks.c
  +om

  # Be kind. Wait between fetches longer than each fetch takes.
