Review Comment:
Immature idea:
As we computed this `minDocIDRunEnd` anyway, can we just collect this range
and update min to it? Probably like:
```
if (minDocIDRunEnd > min + 1) {
rangeDocIdStream.from = min;
rangeDocIdStream.to = minDocIDRunEnd;
collector.collect(rangeDocIdStream);
min = minDocIDRunEnd;
if (minDocIDRunEnd >= bitsetWindowMax) {
// We have a large range of doc IDs that all match.
return minDocIDRunEnd;
}
}
```
I wouldn't expect this to help much since it only happens at the edge of the
range, but it also doesn't seem to have side effects.
