[jira] [Created] (LUCENE-9446) Boolean rewrite could remove more MatchAllDocsQuery filters

Julie Tibshirani created LUCENE-9446:
----------------------------------------

             Summary: Boolean rewrite could remove more MatchAllDocsQuery filters
                 Key: LUCENE-9446
                 URL: https://issues.apache.org/jira/browse/LUCENE-9446
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Julie Tibshirani


It seems that BooleanQuery rewrites will remove a MatchAllDocsQuery 'filter' clause only if there is at least one 'must' clause. I think we could also remove the 'filter' clause if there are no 'must' clauses, but at least one other 'filter' clause.

This could let queries like {{#field:value #*:*}} be rewritten to {{#field:value}}.
