Getting ready

You need an up-and-running Elasticsearch installation, as we described in Downloading and installing Elasticsearch recipe in Chapter 1, Getting Started.

To execute these commands, HTTP clients can be used, such as curl (https://curl.haxx.se/), postman (https://www.getpostman.com/), or others. I suggest using the Kibana console as it provides code completion and better character escaping for Elasticsearch.
