> Computing scores on top hits is fine, but the current way it is implemented -
> at collection time - requires to read/decode more freqs/norms and compute
> more scores than necessary. It would be more efficient to compute scores of
> top hits as a post-collection step by only advancing the scorer to hits that
> made the top-N list.
