> We added IS.searchAfter(Query, Filter) but we don't support Sort yet with this API.
> I think it might be overkill at least at first to try to implement 12 collector variants
for this.
> I put the following idea on SOLR-1726:
> One idea would be to start with one or two implementations (maybe in/out of order) for
the sorting case, and dont overspecialize it yet.
> * for page 1, the ScoreDoc (FieldDoc really) will be null, so we just return the normal
impl anyway.
> * even if our searchAfter isnt huper-duper fast, the user can always make the tradeoff
like with page-by-score. they can always just pass null until like page 10 or something if
they compute that it only starts to 'help' then.
