Review Comment:
Thanks for the suggestion! This case is actually trying to handle the
scenario when there's 0 clause, upon which `WANDScorer` may throw assertion
exception due to the following check:
```
if (minShouldMatch >= scorers.size()) {
throw new IllegalArgumentException("minShouldMatch should be < the
number of scorers");
}
```
However, upon digging further, I think the current code is still not enough,
as `optionalScorers` can still have a size of 0 later on as well if there's no
scorer for a clause for certain segment. I've updated it to
https://github.com/apache/lucene/pull/1039/commits/511d1b2b2b6ffe8994d839a05830b2f629e0e0e3
to catch that scenario as well.
