[https://issues.apache.org/jira/browse/LUCENE-8014](https://issues.apache.org/jira/browse/LUCENE-8014)  
As we can see from the link above, SimScorer.computeSlopFactor and SimScorer.computePayloadFactor were removed in 7x.

What if i need payloadfactor? How can i get this information inside the similarity?  
My purpose is very simple, scored by the sum of the matched terms' payload.  
e.g, we have text "i|1.2 see|2.3 a|0.1 quick|2.9 fox|3.3", analyzed by the delimited\_payload filter and whitespace analyzer, as i search "quick fox", this doc scored 6.2(2.9+3.3).

Is there an alternative way to solve this?
