Subject Re: Group only top 50 results not All results.

You could also return the top 50 groups. That will certainly contain the top
50 responses. The app layer could then do some local sorting to figure
out what was correct. Maybe you'd be returning 3 docs in each or something...

I'd probably only go there if Michael's approach didn't work out though.

and add the facet parameters on that query.

query.
