Hi Yonik, Oh, this is great. Is distributed faceting available in the trunk? What is the basic server setup needed for trying this out, is it cloud with HDFS and SOLR with zookepers? Any chance to see the related documentation? :)

It was only my guess, that if you have MR as computational model and a cloud beneath it, you could naturally map facet fields to their counts inside single documents (no matter, where they are, be it shards or "single" index) and pass them onto reducers. > -Yonik > http://www.lucenerevolution.org -- Lucene/Solr User Conference, May > 25-26, San Francisco > -- Regards, Dmitry Kan
