Hi,

I have the following problem, I am trying to use date_histogram facet on
nested object. Please check the mapping, data, query and the result here:

The result for facet1 is empty, could you help me fix this issue ? I have
the same situation when I follow the example from here:
http://www.elasticsearch.org/guide/reference/api/search/facets/ (Facets
with the nested types), the result for facet1 is empty.

Thanks.
Best regards.

It's interesting, after upgrading ES from 0.19.3 to 0.19.4 the query works
fine and returns correct results.
