Managing documents

The native APIs for managing documents (index, delete, and update) are the most important after the search ones. In this recipe, we will see how to use them. In the next recipe we will proceed to bulk actions to improve performance.

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 of this chapter, present on Packt's website, and on GitHub (https://github.com/aparo/elasticsearch-cookbook-second-edition). The referred class is DocumentOperations.

How to do it...

For managing documents, we will perform the following operations:

• We'll execute all the document's CRUD operations (Create, Update, Delete) via a native client using the following code:

  import org.elasticsearch.action.delete.DeleteResponse;
  import org.elasticsearch.action.get.GetResponse;
  import org.elasticsearch.action.index.IndexResponse;
  import org.elasticsearch.action.update.UpdateResponse...
