> If-Condition to check payload null value in _PayloadScoreQuery.java_ was 
> removed in LUCENE-8038. Because of that, regarding of the payload value, 
> _payloadsSeen_ is always getting increment. This has compromised the overall 
> score of the document(for instance, as payloadSeens is always greater than 0, 
> docScore() in _MinPayloadFunction.java_ only returns payloadScore which can 
> be zero depending on the payload value). Ideally, it should've returned 1 in 
> case of _payload==null_.
> I have added a simple patch to get started, Please let me know if it needs 
> any improvements. 
> Thanks in advance.
