[jira] [Commented] (LUCENE-7587) New FacetQuery and MultiFacetQuery

Michael McCandless commented on LUCENE-7587:
--------------------------------------------
These helper classes look great, thank you [~ekeller].
Maybe add javadocs explaining that this is an alternative to {{DrillDownQuery}}, especially in cases where you don't intend to use {{DrillSideways}}?
