parveen saini updated SOLR-17757:
---------------------------------
Description:
On migrating solr version from 5.5.4 to 8.9.0 I noticed that TFIDFSimilarity
scoring is different and results in different overall score for the query.
On digging deeper I found idf is factored twice in version 5.5.4 which is
causing the issue. Is the change in version 8.9.0 intentional?
