* changes in DenseConjunctionBulkCollector is matching too many documents due to scoreWindow logic * will raise an issue in Lucene to track this * for now collect ourself * this optimization only runs on card agg without sub, and only within the pruning optimization * worst case we can disable this optimization via index setting Signed-off-by: Asim Mahmood <asim.seng@gmail.com>

@asimmahmood1 looks like a good fix. Tbh, i don't mind keeping this logic long term here as dynamic pruning collection logic shouldn't care about any lucene optimizations in future. Should we still create a lucene issue for possible regression if it is applicable in other queries? |

+1 Not the first time this optimization gets affected by Lucene change. It's better to collect in this way, directly reuse the related logic from DefaultBulkScorer. |
