I'm not sure if this is normal in ES2, but in ES1 this is not happening.

I don't have anything in my config, with field data, ie indices.fielddata.cache.size. indices.breaker.fielddata.limit, etc.

When I perfrom a search, I see some fielddata activity in `_nodes/stats/indices/fielddata?fields=*` and `_cat/fielddata` but after a few seconds they are down to 0. The `evictions` is constantly `0`.

```auto
breakers tripped: 0
evictions: 0

```

I can see in `_nodes/stats/indices/fielddata?fields=*`:

```auto
fielddata: {
memory_size_in_bytes: 11736472,

```

then refresh, and it's:  
`memory_size_in_bytes: 3912,`

Also, here's what the marvel chart looks like: [http://imgur.com/a/aXUYh](http://imgur.com/a/aXUYh)

What could be causing this?
