LUCENE-10412: Improve handling of MatchNoDocsQuery in rewrites. (#664)



> Improve handling of MatchNoDocsQuery in rewrite rules
> -----------------------------------------------------
>
>                 Key: LUCENE-10412
>                 URL: https://issues.apache.org/jira/browse/LUCENE-10412
>             Project: Lucene - Core
>          Issue Type: Wish
>            Reporter: Adrien Grand
>            Priority: Minor
>
> Having MatchNoDocsQuery in your query tree usually doesn't make the query 
> slower, but by recognizing it in rewrite rules, we could perform rewrites 
> which would then sometimes unlock other rewrite rules.
> For instance if you have a boolean query with 2 should clauses where one is a 
> MatchAllDocsQuery and the other one is a MatchNoDocsQuery, we would naively 
> run it as a disjunction today, while we could rewrite it to a 
> MatchAllDocsQuery and leverage its specialized bulk scorer.
