Could this perhaps have anything to do with the changes to DocIdSetIterator?
Glancing at the default implementation of advance makes me wince a bit:
public int advance(int target) throws IOException {
while (nextDoc() < target) {}
return doc;
}
IMO, this is a back-compatibility anti-pattern. It would be better to
throw an exception then quietly slow down some of the users queries by
an order of magnitude. Actually, I don't think I would count it as
back compatible because of that.
