Hoss Man updated SOLR-8261:
---------------------------
Attachment: SOLR-8261.patch
Quick patch extracted from my older patch in SOLR-8057 ...
* SchemaSimilarityFactory udpated to use BM25 if luceneMatchVersion >= 6
* cloned TestPerFieldSimilarity as TestPerFieldSimilarityClassic
** TestPerFieldSimilarityClassic set's older luceneMatchVersion
** TestPerFieldSimilarity updated to account for new BM25 defaults
...tests & precommit currently pass, but I want to re-review more closely in
isolation and think about any other tests that should be added before
committing.
> Change the wrapped per-field default in SchemaSimilarityFactory to BM25
> (conditional on luceneMatchVersion for backcompat)
