In Kibana 5.2.2 I created an index pattern `news-*`. Now I would like to filter for `language:english` and show counts split up by real index names.

I thought about using the terms aggregation, but it only includes "internal" `_type`, but not `_index`. Is there a way to aggregate over `_index` in Kibana?

Hi

With \_index, elasticsearch tells kibana, aggregating and searching on \_index is not allowed as by default as it has no index property. If you have `index.raw` in your field mappings then you can aggregate over that field.

In my simple experiment I tried this .

```auto
{
  "logstash-0" : {
    "mappings" : {
      "_default_" : {
        "dynamic_templates" : [
          {
            "string_fields" : {
              "match" : "*",
              "match_mapping_type" : "string",
              "mapping" : {
                "fields" : {
                  "raw" : {
                    "type" : "keyword"
                  }
                },
                "type" : "text"
              }
            }
          }
        ],

```

also there is a ref ticket you could get more info on [https://github.com/elastic/kibana/issues/4027](https://github.com/elastic/kibana/issues/4027)

Hope this helps.
