Recently, we were discussing moving away from out good ol’ Solr-based search engine to a more distributed environment on top of ElasticSearch, first thing I did is listing all the features I was actively using in Solr and compare them one-to-one with their ElasticSearch counterparts. I’m listing my full comparison below.
Note that this list is not a comprehensive list of all Solr features, rather it’s a realistic view of a live Solr setup.
