The pk (primary key) in DIH is only relevant in the context of DIH, and is only used by DIH for validating and coordinating database queries. It has absolutely no impact on the Solr index. If you want a newly indexed document to replace an existing document, the value in the uniqueKey field (defined in schema.xml) must be the same as that field's value in the existing document that you wish to replace. If you have a matching value, Solr will automatically replace the document for you -- the old version will be deleted before the new one is indexed. Thanks, Shawn
