|

|
||||
* SOLR-2670: Added NIOFSDirectoryFactory (yonik)
|
||||
|
||||
* SOLR-2523: Added support in SolrJ to easily interact range with facets.
|
||||
The range facet response can be parsed and is retrievable from the
|
||||
QueryResponse class. The SolrQuery has convenient methods for using
|
||||
range facets. (Martijn van Groningen)
