I am used to hll in the context of count distinct values -- cardinality. I have to admit that section https://lucene.apache.org/solr/guide/8_4/the-stats-component.html#local-parameters-with-the-stats-component is about hll and facets, but I am not sure that really meet the use case. I also have to admit that part is quite cryptic to me. -- nicolas paris
