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 need an up-and-running Elasticsearch installation as we described in the Downloading and installing Elasticsearch recipe in Chapter 2, Downloading and Setup.

A Maven tool, or an IDE that natively supports it for Java programming such as Eclipse or IntelliJ IDEA, must be installed.

The code for this recipe is in the chapter_14/nativeclient directory and the referred class is IndicesOperations.

How to do it...

An Elasticsearch client maps all index operations under the admin.indices object of the client. All the indices operation are here (create, delete, exists, open, close, optimize, and so on).

The following code retrieves a client and executes the main operations on indices:
