> Some queries heavily use hierarchy relations to resolve location steps. E.g.
> ChildAxisQuery or DescendantSelfAxisQuery. Currently those hierarchy
> relations are looked up from the native lucene index which is not very
> efficient. The index should maintain a cache of frequently used hierarchy
> lookups.
> That is, calls like IndexReader.termDocs() on terms with field: UUID or PARENT
