An object is a base structure (analogous to a record in SQL). Elasticsearch extends the traditional use of objects, thus allowing for recursive embedded objects.
Mapping an object
Getting ready
You need an up-and-running Elasticsearch installation as we described in the Downloading and installing Elasticsearch recipe in Chapter 1, Getting Started.
To execute the commands, any HTTP client can be used such as curl (https://curl.haxx.se/), postman (https://www.getpostman.com/), or similar. Again, I suggest using Kibana console, which provides code completion and better character escaping for Elasticsearch.
