Show HN: I wrote a book about Elasticsearch and I'm making it free for students

Hi! Most of us learn a new technology by reverse-engineering what works elsewhere. So I've published a handbook with carefully curated practical examples that demystify the Elasticsearch query language and provide a solid foundation to build on.

If you're a student (or a teacher), send me a proof of your student/teacher status (e.g. a school email address) to joe@elasticsearchbook.com and I'll give you free access to the book.

Cheers!
