I'm amused at the traction this little gist is getting on Google! I would be remiss not to point out that six+ years later I'm still helping thousands of companies on a daily basis with their search index management, by providing managed Solr as a service over at Websolr, and hosted Elasticsearch at Bonsai. Check us out if you'd like an expert helping hand at Solr and Elasticsearch hosting, ops and support!
