It does aggregations that might work for you.

I guess it would also work if I could facet on the group counts. I just
need to know how many groups of different sizes there are.

I am on 6.1 preview, I just need this to gather some one time metrics so
performance isn't an issue.

pre-processing isn't very dynamic though so there are lots
of situations where that's just not viable.

What version of Solr? Regardless, if you can pre-process
at index time it'll be faster than anything else (probably).

pre-processing isn't very dynamic though so there are lots
of situations where that's just not viable.

Filtering on nGroups

[Nick Vasilyev]

I am grouping documents on a field and would like to retrieve documents
where the number of items in a group matches a specific value or a range.

I haven't been able to experiment with all new functionality, but I wanted
to see if this is possible without having to calculate the count and add it
at index time as a field.

Does anyone have any ideas?

Thanks in advance
