Managing indices with the native client

In the previous recipe we saw how to initialize a client to send calls to an ElasticSearch cluster. In this recipe, we will see how to manage indices via client calls.

Getting ready

You will need a working ElasticSearch cluster and a working copy of Maven.

The code of this recipe is in chapter_10/nativeclient in the code bundle, which can be downloaded from Packt's website, and on GitHub (https://github.com/aparo/elasticsearch-cookbook-second-edition). The referred class is IndicesOperations.
