> {{TaxonomyFacetSumValueSource}} has a bug in the way it provides scores to the user-provided doc values. [On this line|https://github.com/apache/lucene/blob/main/lucene/facet/src/java/org/apache/lucene/facet/taxonomy/TaxonomyFacetSumValueSource.java#L78] it should be {{index = doc}}, not {{index++}}. Thanks to [~mikemccand] for finding this over in #718!
> I've reproduced with a test and will post the test and a fix shortly.
