Subject Re: DrillSideways accepting FacetCollector parameter
Date Mon, 14 Jul 2014 23:43:09 GMT
This is right, except, if "wordcount" is one of the drill-sideways
dims, you should use the drill-sideways collector instead of the
drill-down one?

Ie, once the user actually drills down on wordcount (if you expose
that in your UI), you should no longer use the drill-down collector
when faceting that drill-down query.
