Re: Pivot Facets refining datetime, bleh

[Stein Gran <st...@softwaredynamics.no>]

This may be more suitable on the dev-list, but distributed pivot facets is
a very powerful feature. The Jira issue for this is SOLR-2894 (
https://issues.apache.org/jira/browse/SOLR-2894). I have done some testing
of the last patch for this issue, and it is as Andrew says: Everything but
datetime fields works just fine. There are no error messages for datetime
fields when used in a SolrCloud setup, the expected values are just not
there.

Best,
Stein J. Gran
