> Currently we only check whether boolean queries have too many clauses. However there are other ways that queries may have too many clauses, for instance if you have boolean queries that have themselves inner boolean queries.
> Could we use the new Query visitor API to move this check from BooleanQuery to IndexSearcher in order to make this check more consistent across queries? See for instance LUCENE-8810 where a rewrite rule caused the maximum clause count to be hit even though the total number of leaf queries remained the same.
