> whether DocList can even be used for facets, No way. For sure. Overall, FacetComponent explicitly requires docset https://github.com/apache/solr/blob/main/solr/core/src/java/org/apache/solr/handler/component/FacetComponent.java#L82 and then https://github.com/apache/solr/blob/main/solr/core/src/java/org/apache/solr/search/SolrIndexSearcher.java#L1564 https://github.com/apache/solr/blob/main/solr/core/src/java/org/apache/solr/search/SolrIndexSearcher.java#L971 I don't recommend changing anything in this flow.
