Amit Nithian commented on SOLR-4310:
------------------------------------
I apologize for my lack of memory on this... if I recall I don't think it was
anything serious and perhaps something that seemed intuitive but wasn't and I
had to work around it. If your tests show that this works in distributed mode
then it's probably good to go!

> If you group by a field, the response may look like this:
> <lst name="grouped">
> <lst name="series">
> <int name="matches">138</int>
> <int name="ngroups">1</int>
> <result name="doclist" numFound="138" start="0">
> <doc>
> <int name="id">267038365</int>
> <str name="name">
> Larry's Grand Ole Garage Country Dance - Pure Country
> </str>
> </doc>
> </result>
> </lst>
> </lst>
> and if you specify group.main then the doclist becomes the result and you
> lose all context of the number of groups. If you want to keep your response
> format backwards compatible with clients (i.e. clients who don't know about
> the grouped format), setting group.main=true solves this BUT the numFound is
> the number of raw matches instead of the number of groups. This may have
> downstream consequences.
> I'd like to propose that if the user specifies ngroups=true then when
> creating the returning DocSlice, set the numFound to be the number of groups
> instead of the number of raw matches to keep the response consistent with
> what the user would expect.
