Can the name of the bucket aggregation key name be modified?

Hi There,

Can the name of the bucket aggregation key name be modified?

I was looking through the documentation and Google and could not find a way to modify the name of the key returned in the aggregation results. Ideally I would want the results to include the key of the item it represents. In this case "key" --> "circuit.type.id"

Thanks,

Mark

    }
  ]

You can't modify the key, but you can add metadata: https://www.elastic.co/guide/en/elasticsearch/reference/current/agg-metadata.html
