Review Comment:
I wonder if we could (should?) use radix sort directly instead of going
through `StringSorter`? We don't need the fallback sort logic that StringSorter
provides right? Then we could avoid the API visibility change. Maybe there's a
good reason though to go through StringSorter I'm missing?
I _think_ this would do the trick though right?
```
new MSBRadixSorter(Integer.MAX_VALUE) {
@Override
protected int byteAt(int i, int k) {
BytesRef b = sortedTerms[i];
if (b.length <= k) {
return -1;
}
return b.bytes[b.offset + k] & 0xFF;
}
@Override
protected void swap(int i, int j) {
BytesRef b = sortedTerms[i];
sortedTerms[i] = sortedTerms[j];
sortedTerms[j] = b;
}
}.sort(0, sortedTerms.length);
```
