StandardFilter and StandardFilterFactory removed in Lucene 8.x

Hi,-

I hope everyone is doing great.


What replaces these classes in Lucene 8.x?

https://issues.apache.org/jira/browse/LUCENE-8356 says they presumably 
do nothing. Is that certain please?


On the other hand: I see that (for example) the Query class has been 
changed quite a lot when someone wants to switch from Lucene 7.x to 
Lucene 8.x.

For example: the boolean type variable needsScore becomes ScoreMode 
object parameter in some Java public apis such as createWeight method of 
Query class:

https://lucene.apache.org/core/8_1_1/core/org/apache/lucene/search/Query.html


Best regards
