[Koha] Elasticsearch setup

[Tom Hanstra]

I have managed to get elasticsearch running (thanks Thomas!) and it seems
to have indexed many of my records (though there were quite a few errors
and messages received during the indexing process).

Now, how do I best check to see what is in the Elasticsearch index? Is
there a way to test or at least count the number of records indexed?

And then how do I switch Koha from using Zebra to using Elasticsearch?  Do
I have to "turn off" Zebra in some way and turn on Elasticsearch?  Or is
that supposed to be switched automatically?

Thanks in advance for any tips that might help!
