Delete Index in Elasticsearch

An existing index/type/document in Elasticsearch can be deleted either by using REST service or by using the Java API invocation.

Below are the scripts to delete the index.

Delete complete index :

REST  Service:

$ curl -XDELETE 'http://localhost:9200/<indexname>'

Java API :

client.admin().indices().delete(new DeleteIndexRequest("<indexname>")).actionGet();

Delete a type in index   :

REST Service :

$ curl -XDELETE 'http://localhost:9200/<indexname>/<typename>'

Java API :

client.prepareDelete().setIndex("<indexname>").setType("<typename>").setId("*").execute().actionGet();

Delete a particular document :

REST Service :

$ curl -XDELETE 'http://localhost:9200/<indexname>/<typename>/<documentId>

Java API:

client.prepareDelete().setIndex("<indexname>").setType("<typename>").setId("<documentId>").execute().actionGet();

Note:

The delete operation cannot be rolled back at any point. So make sure to double check the delete command before execution.
