The Elasticsearch API reference provides examples of requests in various languages, including Java, available in the dropdown menu on the right.
The sections below provide tutorials on the most frequently used and some less obvious features of Elasticsearch.
For a full reference, see the Elasticsearch documentation and in particular the REST APIs section. The Java API Client follows closely the JSON structures described there, using the Java API conventions.
