Thanks all!   It's really great learning.  A bit off the topic, after I
enabled facet.method = uif in solr cloud,  the faceting performance is
actually much worse than the original fc( ~1000 ms with uif  vs ~200 ms
with fc). My cloud has 8 shards with 6 replicas in each shard.  I do see
that fieldValueCache is getting utilized.  Any reason uif could be so
slow?
