: Was there an intended change on the 'facet_fields' response from Solr's : ruby/python format on the nightly build? Before it was returning a hash but : now it's returning an array. I'm assuming it's a bug...
when upgrading Solr, it's always good to check the CHANGES.txt file -- even when using nightly builds, diffing them can tell you what's diferent. this was added recently... The JSON response format for facets has changed to make it easier for clients to retain sorted order. Use json.nl=map explicitly in clients to get the old behavior, or add it as a default to the request handler in solrconfig.xml -Hoss
