By the way, the funny loop is the same in IndexSearcher.rewrite. ;-)

> It is sometimes desirable to ignore differences between index statistics of several terms
so that they produce the same scores, for instance if you resolve synonyms at search time
or if you want to search across several fields. Elasticsearch has been using this approach
for its multi_match query for some time now.
> We already blend statistics in TopTermsBlendedFreqScoringRewrite (used by FuzzyQuery)
but it could be helpful to have a dedicated query to choose manually which terms to blend
stats from.
