Is it possible to exclude certain fields from particular indexes when performing aggregations?

I've got a multi language indexes which I search across. I only wish to aggregate on my "english" index on the following field

```
  "languageCode": {
                  "type": "keyword",
                  "index": true
               },

```

For my other languages indexes is it possible to exclude this languageCode field from aggregations?

In version 2, I just used used to use this mapping in non-English indexes

```
"languageCode": {
                  "type": "string",
                  "index": "no"
               },

```

But this is no longer an option

I managed to ignore the fields in non-English indexes by configuring it like so:

```
   "languageCode": {
                  "type": "keyword",
                  "ignore_above": 0
               },

```

Is it the correct way of doing this or is there a different method?
