Using the Elasticsearch official Java client

The official Java client is built on top of a low-level one and provides strong typed communication with Elasticsearch.

Initially released with Elasticsearch in the latest versions of 7.15 or above, this client is the official Java client for Elasticsearch 8.x. It provides many extra functionalities, such as the following:

• Integration from application classes to JSON instances via an object mapper such as Jackson
