The author lived up to the expectations of the book title, especially the book serving as "Quick Start Guide" and I am thankful to it. In days of chaotic full-stack development and technology changes, you need a go to book for quick refresher on topics. This book serves that purpose and in fact has gone beyond in the sense that that author also shares some of the best practices based on his experience which are both valid and unfortunately no practices in many implementations.
If your team is using Elasticsearch, I would recommend you have at least a copy of this book as team's go to reference manual.
