Looks like pivot facet with solrcloud does not work (I am using Solr 4.1). The query below return no pivot search result unless I added "&shards=shard1".
http://localhost:8995/solr/collection1/select?q=*%3A*&facet=true&facet.mincount=1&facet.pivot=source_domain,author&rows=1&wt=json&facet.limit=5 When this JIRA (https://issues.apache.org/jira/browse/SOLR-2894) will be implemented? Thanks, Ming-
