* SOLR-2383: /browse improvements: generalize range and date facet display
(Jan Høydahl via yonik)
* SOLR-2272: Pseudo-join queries / filters. Examples:
To restrict to the set of parents with at least one blue-eyed child:
fq={!join from=parent to=name}eyes:blue
To restrict to the set of children with at least one blue-eyed parent:
fq={!join from=name to=parent}eyes:blue
