Access aggregation key inside script

[Wullschi]

Hi, I have a filter script inside an Aggregation. Inside this script i would like to access the key from the outer Aggregation. Is this possible?

"aggs": {
        "category": {
          "terms": {
            "field": "category",
            "size": 20
          },
          "aggs": {
            "my_filter": {
              "filter": {
                "script": {
                  "lang":   "painless",
                  "inline": "if(category_key == 'phone'){do something}else{do something else}"
                }
              }
            }
          }
        }
      }

Thanks!

It's not possible for aggregations to access the key for the bucket they are in. To achieve what you want you could split your terms aggregation into two separate aggregations; a filter aggregation for category:phone which contains the filter you want to apply on the phone documents, and also a terms aggregation similar to your current one but with "excludes": "phone" so the phone documents do not appear in this aggregation since you already have that in the separate filter aggregation.

Hope that helps.
