Eliminate spurious "extra" query normalization
----------------------------------------------
Key: LUCY-183
URL: https://issues.apache.org/jira/browse/LUCY-183
Project: Lucy
Issue Type: Bug
Components: Search
Affects Versions: 0.2.1 (incubating), 0.2.0 (incubating), 0.1.0 (incubating)
Reporter: Marvin Humphrey
Assignee: Marvin Humphrey
Fix For: 0.2.2 (incubating), 0.3.0 (incubating)
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.
