      Description

      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.
