Raise error during bulk POST if an index document with identical _id already exists?

I can see that for non-bulk PUT operations this functionality exists, for the _id field, using "op_type" as explained in the API.

So I tried this URL:

https://localhost:9200/my_index/_bulk/?op_type=create

and also

https://localhost:9200/my_index/_bulk?op_type=create

Both failed:

"error": {
    "reason": "request [/my_index/_bulk/] contains unrecognized parameter: [op_type]",

Is there any way to accomplish this? The request body is the bulk string itself and the method is POST.

>Solution :

You just need to use create instead of index in _bulk

DELETE test

POST test/_bulk?refresh
{"create": {"_id": "foo"}}
{"test": 1}
{"create": {"_id": "foo"}}
{"test": 2}

POST test/_search
{
  "query": {
    "match_all": {}
  }
}
