@mmiklavc I'd be happy to write-up your feedback as another PR. Its
definitely really good info (especially (6) ES client is intimidated by
ElasticsearchUtils :) ), but I don't want to steal your thunder. If you don't
have time to get to it, just let me know and I'll write it up in a separate PR.---
