Review Comment: non-distributed (means Standalone non-SolrCloud mode, distrib=false and when *paginated*) we need some work in the upcoming PR, where similar logic (as in the case of distrib=true) of fetching all docs right from start and selecting the r rows based on `ShardFieldSortedHitQueue` needs to be implemented.
