Hi,

I don't understand your question. Filter queries no longer exit since Lucene 6! 
If you want to filter, use any query and pass it as BooleanClause.Occur.FILTER 
to aBooleanQuery. Done.

Those FILTER clauses may (depending on the query type) perform better than MUST 
clauses, because no score is calculated.
