Tim Owen commented on SOLR-7830:
--------------------------------
I've attached a new patch, I took your original patch and updated it for the 7x
branch, then added distributed search support (the merging and re-sorting).
We wanted this functionality as it's really useful to fetch 1 or 2 sample
documents with each bucket for some of our use-cases, and this approach of
using the topdocs aggregate function works really nicely.
The only limitation is that the sorting for distributed searches can only work
with field sorting, not with functional sorting, and you can only sort by
fields that are included in the results (otherwise it would need to include the
sort values in shard responses - this could be done, but it was more complex
and we didn't need that for our use-case). Also, the offset parameter isn't
used, but we felt pagination of these topdocs was quite niche (but it could be
added to this patch).

> A topdocs() facet function would return the top N documents per facet bucket.
> This would be a big step toward unifying grouping and the new facet module.
