That's interesting thanks for sharing. I've used Elasticsearch and found all the configuration tuning daunting, but I'm sure I would go through that with Solr as well. I never used ES as a primary data store and I had jobs syncing it up so data loss was never a real concern for me.
I just clustered ES with Docker somewhat recently. It was pretty good at discovery I must say. Well, I'm no great search engineer I just throw these things up when I need 'em so good to know all this. Thanks again.
