Yonik, Just curious why does using enum improve the facet performance.
Furkan was faceting on a text field with each word being a facet value. I'd imagine that'd mean there's a large number of facet values. According to the documentation (http://wiki.apache.org/solr/SimpleFacetParameters#facet.method) facet.method=fc is faster when a field has many unique terms. So how come enum, not fc, is faster in this case? Also why use filterCache less?
