Batch Uploading Documents

Uploading documents of a single type

POST /{INDEX_NAME}/{TYPE}/_bulk?pretty

{"index":{"_id":"1"}}
{"name": "John Doe" }
{"index":{"_id":"2"}}
{"name": "Jane Doe" }

Bulk Updating documents

This example updates the first document (ID of 1) and then deletes the second document (ID of 2) in one bulk operation:

POST /{INDEX_NAME}/{TYPE}/_bulk?pretty

{"update":{"_id":"1"}}
{"doc": { "name": "John Doe becomes Jane Doe" } }
{"delete":{"_id":"2"}}

Note above that for the delete action, there is no corresponding source document after it since deletes only require the ID of the document to be deleted.

Uploading documents of different types

POST localhost:9200/_bulk

{ "index" : { "_index" : "test", "_type" : "type1", "_id" : "1" } }
{ "field1" : "value1" }
{ "delete" : { "_index" : "test", "_type" : "type1", "_id" : "2" } }
{ "create" : { "_index" : "test", "_type" : "type1", "_id" : "3" } }
{ "field1" : "value3" }
{ "update" : {"_id" : "1", "_type" : "type1", "_index" : "index1"} }
{ "doc" : {"field2" : "value2"} }
