With some more digging, what we found is that `DisjunctionScorer` will utilize a cached view of its `TwoPhase.verifiedMatches` on a later document. This will cause the `getSubMatches` to be completely wrong, matching a `NO_MORE_DOCS` value. I am not sure why this is the case, `TwoPhaseIterator.asDocIdSetIterator(twoPhase);` should be calling `matches()` on every doc. But there apparently is a case where this doesn't happen. Whatever the cause, `approximation` and `TwoPhase#verifiedMatches` get out of sync in `DisjunctionScorer` when used in `MaxScoreBulkScorer` (the underlying scorer in this case was also a PhraseScorer). Still trying to figure out why these get out of sync :/ -- This is an automated message from the Apache Git Service.
