Thanks for reply.

We have an issue with not working aggregations  
([Aggregations stop working silently on elasticsearch 1.4.4](https://discuss.elastic.co/t/aggregations-stop-working-silently-on-elasticsearch-1-4-4/28480))  
Could this mapping be an issue (child type field has doc\_values: true and parent type does not) ?

```
           contact: {
              properties: {
                contact_id: { type: 'long', index: 'not_analyzed'}
              }
            },
            event: {
              _parent: { type: :contact },
              properties: {
                user_id: { type: 'long', index: 'not_analyzed' },
                contact_id: { type: 'long', index: 'not_analyzed', doc_values: true },
                data: { type: 'object', index: 'not_analyzed' },
              }
            }

```
