yes, route as well as id parameter is required if the collection is sharded
on any other field than the unique id. This feature was broken in solr
prior to 8.10. It was fixed with this jira -
https://issues.apache.org/jira/browse/SOLR-8889.
Multiple ids with route can be deleted by using update request object
directly
UpdateRequest req = *new* UpdateRequest();
for(solr docs) {
req.deleteById(docId, route); //added to hashmap internally
}
req.process(client, collection)
