> In the case needsScores=false, createWeight calls rewriteNoScoring before 
> creating a new BooleanWeight. This in all cases creates a new BooleanQuery, 
> even when it's not necessary (aka there are no MUST clauses). 
> The rewriteNoScoring method could check for something as simple as if 
> (clauseSets.get(Occur.MUST).size() > 0)  before creating a brand new 
> BooleanQuery.
