I'd start by checking if the relevant process (probably qcluster) is
actually running -- in my experience the most common reason for ZERO
logs is the process isn't running.
I'll tell you what I'd do after that *because* a developer should
track this stuff down, but if everything failed, purely as a matter of
debugging I'd just change the default in the update_index function to
verbosity=1, then change it back (or to 2, etc) once you have whatever
information that gives you. That's what I recommend you do once you
have confirmed the process is running.
Then while waiting on the user channels I'd grep for 'search_indexes'
in import statements to see where search_index.update_index is called
to see how that 'verbosity' parameter gets set. It may be ignored
(defaulted to 0) or hardcoded, but there may also be a option that can
be set in the LOGGING parameter of settings.py.
If that doesn't work, I'd trace back through the imports and scan
source to try to find alternative logging options for django_haystack,
since you're not actually that interested in the HyperKitty function
which does no real work.
The thing is that phrase "no real work". Even the verbosity parameter
delegates the logging to third-party code. The work here is being
done by third-party code in Django and django_haystack, plus whatever
indexer you're using (Whoosh or Xapian). Probably all of these have
many options for logging.

Sure, but it's going to be a "patches welcome" HyperKitty issue
because all HyperKitty can tell you is the command was called.
Haystack can tell you that too, and a lot more. django_q (which
calls the HyperKitty tasks) probably can too.
OTOH, we should document third-party logging better. Note, that
doesn't require Mailman developers, non-developer contributors can do
that too.
