Review Comment:
@iverase agreed when actually using the doc values, but I'm curious how
performance would compare against using the points index if present. Our
current logic is that we will, 1) use points if available to find all hits in
the range, falling back to 2) bsearch over doc values to determine the range. I
figured with this change we'd want, 1) points index, 2) skipper over doc
values, 3) bsearch over doc values. But maybe you're suggesting we should do,
1) skipper over doc values, 2) points index, 3) bsearch over doc values?
