> Key: LUCENE-9446
> URL: https://issues.apache.org/jira/browse/LUCENE-9446
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Julie Tibshirani
> Priority: Minor
> Time Spent: 50m
> Remaining Estimate: 0h

> 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}}.
