There is no right (or wrong) answer. The best way is to test. Start with
the default 5 shards and load real data into it at the rate that you expect
in production. And then query it at the rate that you expect in production

  • check throughput and response times. Then run your facets, sorts,
    aggregations - check throughput, response times, and RAM usage. After a
    little but of testing, you should get a good sense of the limits of your
    hardware (per node) and then go from there.
