Hi Tommaso I don't think you can achieve what you want using vanilla solr. Facet counts will be for the result set matching not for the top n result sets matching.
However what is your use case ? Assuming its for faceted navigation showing facets for the top n result sets could be confusing to your users. As the next incremental filter applied by the user would change the "relevancy focus" of the user and produce another set of top n facet counts with a document set un-related to the last result set. This could be a very bad user experience producing a fluctuating facet counts (ie a filter narrowing the search could produce an increase in a facet term count - very odd) also the result set could change strangely with docs floating in and out of the result list. relevancy seems to be the answer here - if your docs are scored correctly then counting all docs in the result set for the facet counts is correct. do you need to improve relevancy?
