Manuel Lenormand commented on SOLR-5478:
----------------------------------------
Denis - yes, the topN doc ids are read from the stored fields. It happens in
the BinaryResponseWriter.
Robert - you suggest returning the uniqueKey in the SolrQueryResponse? what
stage do think of doing it? what about letting the frontend work with docId,
while being aware of the shard provenance? why after working on solr-3855
didn't you implement the uniquekey read from docValues?
> Speed-up distributed search with high rows param or deep paging by
> transforming docId's to uniqueKey via memory docValues
