Another way is to extend the existing Facets component. FacetsComponent
uses SimpleFacets to compute facets where it passes the matching docset
(rb.getResults.docSet) as an argument in constructor. Instead you can pass
it the ranked docList by passing (rb.getResults.docList).
Basically 3 steps
I agree with Alex a PostFilter would work. But it would be a somewhat
tricky PostFilter to write. You would need to collect the top 50 documents
using a priority queue in the DelegatingCollector.collect() method. Then in
the DelegatingCollector.finish() method you would send the top documents to
th
I don't think either grouping or faceting work as postfilter.
Otherwise, that would be one way. Have a custom post-filter that only
allows top 50 documents and have grouping run as an even-higher-cost
postfilter after that.

So
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.
I suggest doing this in two queries. In the first query, retrieve the unique
ids of the top 50 documents. In the second query, just query for those ids
(e.g., q=ids:(2 13 55 62 81)), and add the facet parameters on that query.
