------------------------------------
bq. Oh, it turns out OBSI.nextDoc is new in 2.9!
Are you sure about it? If so, then why test-tag failed on it? Notice that there
are two methods nextDoc() and next(int). Are both new in 2.9? If so, it means
somebody added them to the tag, for some reason ...
BTW, I'm going to open the follow-up issue to that, so we can discuss whatever
improvements we want to make to the Scorers following the MAX_VAL sentinel
there. Otherwise, they will get lost in this issue, and when we'll handle the
follow-up one, we might not remember everything.
bq. It's called - @Since
That's absolutely a great idea !

> See
> http://www.nabble.com/Another-possible-optimization---now-in-DocIdSetIterator-p23223319.html
> for the full discussion. The basic idea is to add variants to those two
> methods that return the current doc they are at, to save successive calls to
> doc(). If there are no more docs, return -1. A summary of what was discussed
> so far:
> # Deprecate those two methods.
> # Add nextDoc() and skipToDoc(int) that return doc, with default impl in DISI
> (calls next() and skipTo() respectively, and will be changed to abstract in
> 3.0).
> #* I actually would like to propose an alternative to the names: advance()
> and advance(int) - the first advances by one, the second advances to target.
> # Wherever these are used, do something like '(doc = advance()) >= 0' instead
> of comparing to -1 for improved performance.
> I will post a patch shortly
