> In DescendantSelfAxisQuery.DescendantSelfAxisScorer.isValid(int) contextHits is populated
with docs that are found on the way down the axis. The current algorithm unfortunately doesn't
add any new docs at all because it only adds docs already present in contextHits. This leads
to more calls to HierarchyResolver.getParent(int) than necessary.
