Sorry if this is not the right venue for this request!
My soon-to-be-released book, Node.js 8 the Right Way features Elasticsearch prominently. Readers learn to create indices and insert documents, then later how to implement Express-based APIs that perform Elasticsearch queries.
I'm looking for a technical reviewer who can vet the content of the book from the Elasticsearch side of things. I want to live up to the title "the Right Way". I wrote the bulk of the book targeting Elasticsearch version 5.2, so it would be especially helpful if you know the ins and outs of 5.4 and beyond.
Thanks in advance!
