I can't get this [1] to work in 5.x, and the documentation no longer includes aggregations [2]. 1 - [https://www.elastic.co/guide/en/elasticsearch/reference/2.4/mapping-field-names-field.html](https://www.elastic.co/guide/en/elasticsearch/reference/2.4/mapping-field-names-field.html) 2 - [https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-field-names-field.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-field-names-field.html) ---

It looks like this was removed in 2.0 (see: [https://github.com/elastic/elasticsearch/pull/10893](https://github.com/elastic/elasticsearch/pull/10893)) and is no longer configurable (other than enabling or disabling the field). I suspect the documentation was updated to remove the mentions for aggs since it can only be used for queries now. ---

Thanks! Can you think of a way (other than managing the fields myself or using a key/value approach) to solve the same problem? ---
