Hi all,

I'm trying to use expand\_action\_callback function to get back one of the action fields from the streaming\_bulk response. There is "\_id" but I need to access another field which is in the original action.

Am I on the right track? Can expand\_action\_callback be used for this purpose?

Currently I am using a monkey-patch on "streaming\_bluk" function that adds raw data in to the response as a messy work-around.

Accessing my field in the posted actions data as in below example:

```auto
for ok, item, raw_data in streaming_bulk_patch(es, actions):
    print(raw_data['raw_data']['nosql_id'])

```
