[jira] [Updated] (SOLR-8261) Change the wrapped per-field default in SchemaSimilarityFactory to BM25 (conditional on luceneMatchVersion for backcompat)

["Hoss Man (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SOLR-8261?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.
