Say I have clothing types that each have shared and distinct mappings. I can get all of the field mappings using the get mapping API. It seems prior to ES 5, we used to be able to aggregate on \_field\_names in order to get mappings for a particular query. Since this is no longer possible, what is the best way to get this data?

I want to get the mappings for the following query:

```
{ "query": { "bool": { "filter": { "term": { "type": "shirt" } } } } }

```

What is the best way to go about accomplishing this?

Thanks
