> Follow-up of SOLR-8251: APIs and user interfaces sometimes encourage to write
> BooleanQuery instances that are not optimal, for instance a typical case that
> happens often with Solr/Elasticsearch is to send a request that has a
> MatchAllDocsQuery as a query and some filter, which could be executed more
> efficiently by directly wrapping the filter into a ConstantScoreQuery.
> Here are some ideas of rewrite operations that BooleanQuery could perform:
> - remove FILTER clauses when they are also a MUST clause
> - rewrite queries of the form "+*:* #filter" to a ConstantScoreQuery(filter)
> - rewrite to a MatchNoDocsQuery when a clause that is a MUST or FILTER
> clause is also a MUST_NOT clause
