Adrien Grand resolved LUCENE-5499.
----------------------------------
    Resolution: Fixed

I can't find exactly when, but this has been fixed: TopFieldCollector now early-terminates if the search sort is a prefix of the index sort.

>             Project: Lucene - Core
>          Issue Type: Improvement
>            Reporter: Robert Muir
>            Priority: Major
>
> 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
