Subject RE: Json faceting, aggregate numeric field by day?
Date Wed, 10 Feb 2016 12:13:36 GMT
Hi Tom - thanks. But judging from the article and SOLR-6348 faceting stats over ranges is not
yet supported. More specifically, SOLR-6352 is what we would need.

[1]: https://issues.apache.org/jira/browse/SOLR-6348
[2]: https://issues.apache.org/jira/browse/SOLR-6352

Thanks anyway, at least we found the tickets :)

Markus
