Lee Hinman and I have been working hard on a book called Elasticsearch in Action. The book has now entered the Manning Early Access Program (MEAP) which allows you to subscribe to chapters as they become available. You can also use a forum to ask questions or give us feedback before the book goes into print.
Please tweet about Book: Elasticsearch in Action
This is an intermediate level book designed for anyone who’s writing applications that use Elasticsearch or who is responsible for managing Elasticsearch in a production environment. It will offer great coverage of all the key features exposed through the HTTP API, and all code samples will be in bash using curl. This way, it will be easy for you to translate them in any language and to get help from the Elasticsearch community.
