Gregg Donovan commented on SOLR-7406:
-------------------------------------
One minor bit - is the import of org.apache.log4j.Logger in SimpleFacets rather
than SLF4J intended? I noticed this when running faceting within our unit
tests, which don't have log4J on the classpath.
> Support DV implementation in range faceting

> interval faceting has a different implementation than range faceting based on
> DocValues API. This is sometimes faster and doesn't rely on filters / filter
> cache.
> I'm planning to add a "method" parameter that would allow users to choose
> between the current implementation ("filter"?) and the DV-based
> implementation ("dv"?). The result for both methods should be the same, but
> performance may vary.
> Default should continue to be "filter".
