Christine Poerschke commented on SOLR-9643:
-------------------------------------------

Hello [~parasdiwan] - you don't mention whether or not your collection is 
sharded, if it is sharded then the [Distributed Result Grouping 
Caveats|https://cwiki.apache.org/confluence/display/solr/Result+Grouping#ResultGrouping-DistributedResultGroupingCaveats]
 might apply to the behaviour you observe i.e.
bq. ... {{group.ngroups}} and {{group.facet}} require that all documents in 
each group must be co-located on the same shard in order for accurate counts to 
be returned. ...

> Either value of ngroups in grouped query is inaccurate or there is some issue 
> in returning documents of later pages. 
> select?q=*:*&group=true&group.field=family&group.ngroups=true&start=0&group.limit=1
> For above mentioned query i get ngroups = 396324
> but for the same query when i modify start to 396320. it returns 0 docs, an 
> empty page.
> Instead the last result is at 386887.
> Please look into this issue or offer some solution
