_search request. Get only objects / elements inside hits?

Elastic Stack Elasticsearch
1

Hi,

I want to query elasticsearch for exporting a subset of data to be able to import it into a separate elasticsearch instance, which is not connected. Also I need to export as plain text, that the exporter is able to double check data and to render personal data anonymous manually.

The output response for the _search looks like the following:

I want only to have the objects inside hits. I assume that I can just feed these objects to logstash for importing into the other instance.

Is there any option that elasticsearch is just delivering these array elements, or do I need to post process the results to only return the hits' entries?

Thanks, Andreas

Postprocessing is the way to go here, you can use filter_path to only return the hits.hits data structure, but you cannot change the structure and move fields around within Elasticsearch.
