DELETE  is an Elasticsearch API which removes a document from a specific index. This API requires an index name and _id document to delete the document. 

Delete a document

DELETE /my_index/_doc/1
Notes
  • A delete request throws 404 error code if the document does not already exist in the index.
  • If you want to delete a set of documents that  matches a query, you need to use delete by query API.
