To validate this, I indexed the datasets and ran the same query on Solr 6.5.0 environment (https://archive.apache.org/dist/lucene/solr/6.5.0/) before cb9f15 commit gets into release but got the same response, no additional fields, as Solr 8.1.1. I have used the default managed schema settings in both Solr versions, which I guess means qparser is not used for /select in this case, is it?
