Upayavira commented on SOLR-4772:
---------------------------------
Thinking about it, I should convert this to a generic RoundingUpdateProcessor,
that can do numbers too. Would allow folks to use the same technique across
anything you might do range faceting on.

> A simple UpdateProcessor that rounds dates using the DateMathParser.
> At present it is not possible to combine pivot faceting with range queries.
> This simple UpdateProcessor allows us to round our dates on their way into
> Solr, giving us date fields that can be used in pivot facets.
> This can be extremely useful when using facets to plot graphs based upon log
> files indexed into Solr.
