Ahh I see ... so given a single FacetResultNode, you would like to know which documents contributed to its weight (count in your case). This is not available immediately, that's why you need to do a drill-down query. So if you return the user a list of categories, when he clicks one of them, you perform a drill-down query on that category and retrieve all the associated documents.
May I ask why do you need to know the list of documents given a FacetResultNode? Basically in the 3.6 API it's kind of not so simple to do what you want in one-pass, but in the 4.x API (especially the upcoming 4.7) it should be very easy -- when you traverse the list of matching documents, besides only reading the list of categories associated with it, you also store a map Category -> List<docIDs>. This isn't very cheap though ... So I guess it would be good if I understand why do you need to know which documents contributed to which category, before the results are returned to the user.
