I made a bloggity post for Elastic, the company behind Elasticsearch, Logstash and Kibana.
Our list page got 35% faster. Then we took it further: Angular was making over a dozen web requests to get counts of candidates in various buckets - individuals who are skilled in iOS or Node development, individuals who want to work in Los Angeles, etc. We dropped that to a single request and then combined it with the results request. From 13+ HTTP round-trips per search, we got down to one.
