> Query normalization is supposed to scale all scores uniformly by a simple
> multiplier, but the child nodes in complex queries are presently getting
> "extra" normalization applied to them. This has the effect of scaling
> different subqueries by different amounts, changing the balance of the
> subqueries within a complex query, interfering with IDF weighting and subtly
> degrading relevancy.
