Elasticsearch: how to to calculate avg _score on each bucket?

I have a match query and I want to do a terms aggregation (say on field doctype) to calculate on each bucket the average _score of the query. I don't find how to access the _score field within the aggregation. Someone can help? thanks, Patrick

To access score you would need to have scripting enabled. Then you can access the score in document as shown in example below:

"aggs": {
      "type_bucket": {
         "terms": {
            "field": "_type"
         },
        "aggs": {
            "avg_score": {
                "avg": {
                    "script": "_score"
                }
            }
        }
      }
    }
