I'm trying to write an ElasticSearch aggregate query that includes filtering where I am wanting to grab all of the tags off a all of the documents where a user id matches the one I specify.

I have this code:

```
{
  "size": 0,
  "aggs": {
    "tags": {
      "filter": { "term": { "account_id": 123 } },
      "terms": {
        "field": "tag_list",
        "size": 10
      }
    }
  }
}

```

But I get the following error:

```auto
      {
        "type": "parsing_exception",
        "reason": "Found two aggregation type definitions in [tags]: [filter] and [terms]",
        "line": 6,
        "col": 16
      }

```

The document mapping contains a `tag_list` attribute that is an array of tags.

Your request is malformed. You need to nest the terms aggregation inside the filter aggregation like this:

```auto
{
  "size": 0,
  "aggs": {
    "my_filter": {
      "filter": {
        "term": {
          "account_id": 43049
        }
      },
      "aggs": {
        "tags": {
          "terms": {
            "field": "tag_list",
            "size": 10
          }
        }
      }
    }
  }
}

```

Thank you!! I think this is working, but for some reason its not returning all of the collected tags across all documents, even when I remove the `size: 10`

`10` is the default value of `size`, so removing it does not make a difference. Try setting it to `100` or even `1000`.

If you have a very large number of tags, you could also consider wrapping your terms aggregation in a [composite aggregation](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-composite-aggregation.html). The composite agg allows you to paginate through all the buckets.

Thanks @abdon!! I actually figured out my question shortly after asking. I'll look into the composite aggregation. For now, I'll set the size to 1000
