   @jpountz : After a query runs , i read that lucene uses filter cache where it encodes the posting list using compressed bitmaps (roaring) , is there any api to retrieve these compressed bitmap rather than iterating over the actual document ids ?
   
   My use case is some filters can have possibly large hits (>10 million) and in such scenarios the compressed bitmaps can possibly help for downstream logic . Any recommendations or pointers for any other approaches ? 
   For a query is it possible to have a quick dry run to get estimated number of documents it will return ?
