I wrote a book about Elasticsearch / OpenSearch

• gxjoe 5y ago
  Hello all, After hundreds of hours spent on answering questions on stackoverflow, I observed a few barriers of entry that Elasticsearch newbies struggle with. It's first and foremost the formidable query language. 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 query language and provide a solid foundation to build on. Hope it helps!
