> Scorer.visitSubScorers() is protected which make it impossible to implement
> it on a composite scorer in another package.
> I came around this issue when I tried to write a workaround for the 2nd
> problem of this issue: DisjunctionMaxScorer does not implement
> visitSubScorers():
> If you write a Scorer in another package than o.a.l.search and implement
> visit subScorers(), you may need to call the visitSubScorers method
> recursively on your leaves (sub-scorers). But this is not possible, as the
> method is protected.
> This issue should also fix the missing implementation of visitSubScorers in
> DisjMaxQuery.
