Awesome book. I read the pre-release and it was a great deep dive into various topics that will help improve your search application. I highly recommend for anyone who is working with Elasticsearch (I think they also have a Solr appendix, but I was only interested in ES)!

Do you have any thoughts on how it compares with other Elasticsearch books? e.g Elasticsearch in Action has really good reviews on Amazon.

This is not a Elasticsearch focused book. Rather, it is using ES as a tool in order to provide an concrete and practical walkthrough about how to achieve semantic relevancy in real world application. It is not concerning too much about the engineering side of ES, e.g. Master/Datanode or replication that kind of stuff, but more on the quality of text search.

As the author has put, you could use Solr but will still find this book relevant(sorry) to you.

I've only read this and the Definitive Guide to ES. "Relevant Search" is more focused on working through how to tune search results and understand why things are happening and how you can make them work in your favor. They work through a lot of great examples and go much deeper than anything else I've come across.

(author here) -- yeah we focus on relevance exclusively. Other topics like analytics, scale, devops, performance, data integration would be better handled by one of the pure Elasticsearch or Solr books (Solr in Action, ES in Action, ES the Definitive Guide).

Thanks! Ordered. This seems more relevant(sorry) to my needs.

[softwaredoug]

Thanks! Very much appreciated.

Not sure about the other ones but the focus is strictly on quality/relevance of search results.
