Some people in the Elasticsearch community are using random scoring [1]
to sample a document subset from the search results. Maybe something
similar could be implemented for Solr ?
There are probably more efficient sampling solution than this one, but
this solution is likely more straightforward to implement.

Hi,
Is it possible I can sampling based on "search result"?
Like run query first, and search result return 1 million documents.
With random sampling, 50% (500K) documents return for facet, and stats.
The sampling need based on "search result".
Thanks,
