There are multiple pull requests open from last year that negated any performance difference Solr had over Elasticsearch.

This year you used the same flawed code without addressing any of the issues. Elasticsearch is smarter and was able to handle your bad queries better. Even your Solr queries were not optimal last year and can be improved even more this year using the new “filter()” operator available in 5.4.

Im guessing that if you were to address the issues raised in the PR’s and update Solr to use the new filter operator for each “OR” filter your performance would be very similar if not identical.

It’s true when you say these test’s “don’t have particularly significant implications for real world applications”, but the reality is you are out here making claims that are most likely false due to poor test setup.
