Executing a facet search

The previous recipe can be extended to support facet and to retrieve analytics on indexed data.

Getting ready

You 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 of this book available on Packt's website and the referred class is FacetExample.

How to do it...

For executing a facet search, we will perform the steps given as follows:
