You should not give up, starting from 5.5 uif should be there helping and starting from 6.1 term enum is fixed as well.
There is still the logic of forcing a facet approach depending on your config and request parameters [1]. It is not expected you don't solve your problem with docValues either ... Using the json Faceting approach anyway will not imply any particular configuration or jars. it is in Solr out of the box, starting from 5. It is experimental and you may check yourself this APIs changed and improved a lot in late 5 and 6 :) Cheers [1] org/apache/solr/request/SimpleFacets.java:578 : selectFacetMethod -- View this message in context: http://lucene.472066.n3.nabble.com/Upgrade-SOLR-version-facets-perfomance-regression-tp4315027p4317815.html Sent from the Solr - User mailing list archive at Nabble.com.
