We moved everything from SOLR to Elasticsearch about a year ago. We were already using Elasticsearch for data visualizations, but SOLR was our text search. Elasticsearch supported that, and we were able to add more language analyzers to support our use-case. On the admin side, SOLR was a black box to everyone but one person on the team. If a node dies, there needs be another election, and Zookeeper needs to be updated. Restart nodes too fast and we ended up masterless a few times. Elasticsearch is much much better on leader elections and backups, though status going to red on new index creation is obnoxious. That supposedly will be fixed soon.
