Hello Erick, I did look into updatable docValues, but my understanding is that the field has to be non-indexed (indexed="false"). I need to be able to sort on these values. External field fields are sortable. https://lucene.apache.org/solr/guide/6_6/updating-parts-of-documents.html#UpdatingPartsofDocuments-In-PlaceUpdates
