Description

Today collectors, once they collect enough docs, can instruct scorers to update their iterators to skip non-competitive documents. This is applicable only for a case when we need top docs by _score.

It would be nice to also have an ability to skip non-competitive docs when we need top docs sorted by other fields different from _score.
