I'm trying to obtain faceting information based on the first 'x' (lets say 100-500) results matching a given (dismax) query. The actual documents matching the query are not important in this case, so intuitively the simplest approach I can think of would be to limit the result set to 'x' documents.
Unfortunately I can't find any easy way to limit the number of documents matched (and returned in the set). It might be possible to achieve the desired result by using a function query + filter query, however that seems a but hack-ish and hopefully I've missed something basic that leads to a simpler solution. Apologies if this has already been discussed / solved before. Thanks, Piete
