This section describes the Java API that elasticsearch provides. All elasticsearch operations are executed using a Client object. All operations are completely asynchronous in nature (either accepts a listener, or return a future).

Additionally, operations on a client may be accumulated and executed in Bulk.

Note, all the APIs are exposed through the Java API (actually, the Java API is used internally to execute them).

Maven Repository

Elasticsearch is hosted on Maven Central.

For example, you can define the latest version in your pom.xml file:

<dependency>

    <artifactId>elasticsearch</artifactId>
    <version>0.90.1</version>
</dependency>
