Hi David,

I've read through your post in #elasticsearch and have been trying to reproduce your scenario. Unfortunately I'm not having much success. Here's what I'm observing; maybe you can tell me what you are observing that's different:

I installed the mapper-size plugin in Elasticsearch 2.2.0 and creating an index with the following mapping:

```
PUT foo
{
  "mappings": {
    "bar": {
      "_size": {
        "enabled": true
      }
    }
  }
}

```

Then I indexed a couple of documents into it, of varying sizes.

When I create an index pattern for this index in Kibana, I do **not** see the `_size` field in the list displayed by Kibana:

Given that, I cannot use the `_size` field in any visualizations for performing aggregations on it.
