The search-time sort just has to be "congruent" with the index-time one.

> Today EarlyTerminatingSortingCollector requires that the Sort match exactly at query
and at index time.
> However, now that you can use any Sort (e.g. with multiple sortfields), this should be
improved.
> For example, early termination is fine in the following case:
> * index-time: popularity desc, time desc
> * query-time: popularity desc
