     [ https://issues.apache.org/jira/browse/SOLR-8270?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Hoss Man updated SOLR-8270:
---------------------------
    Attachment: SOLR-8270.patch

Patch so far, still vetting/testing...

* IndexSchema
** checks luceneMatchVersion to decide what implicit SimFactory to use
* TestNonDefinedSimilarityFactory
** existing test now asserts schema-tiny.xml will get BM25Similarity
** new test method that sets luceneMatchVersion before initing core and asserts ClassicSimilarity for same schema
* Misc tests updated to account for new BM25 default behavior...
** TestGroupingSearch
** QueryElevationComponentTest
** StatsComponentTest
** TestSchemaSimilarityResource
** ChangedSchemaMergeTest
** TestExtendedDismaxParser
** TestReRankQParserPlugin
** TestSolrQueryParser
** SchemaTest
* TestFunctionQuery
** refactored so that tf/idf function could be tested against a field that explicitly used ClassicSim (these valuesources require TFIDFSimilarity)
*** tweaked schema11.xml to have a ne fieldType with the needed sim for this new refactored test
** one other small tweak needed to testGeneral to account for new BM25 lenghtNorm behavior

> As discussed in parent issue, when the luceneMatchVersion is >= 6.0, IndexSearcher should use BM25SimilarityFactory as the implicit default if no explicit default is configured.
