Re: Scorer#getMinScore()

[Adrien Grand]

Your guesses sound right to me:
 - A query that does subtractions could yield negative scores, which are
not supported.
 - We'd need to store the least competitive impacts for each block of
postings, which would double the amount of CPU and space we spend on
impacts, while min scores would likely be much less frequently useful than
max scores?
