[jira] [Commented] (LUCENE-7730) Better encode length normalization
in similarities
[ https://issues.apache.org/jira/browse/LUCENE-7730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16012832#comment-16012832 ]
Robert Muir commented on LUCENE-7730:
-------------------------------------
I think there is a bit of a trap wrt classicsimilarity, maybe can ClassicSimilarity be moved out of core since it is the only one no longer compatible with the others? e.g. maybe into misc/ or somewhere else.

> Now that index-time boosts are gone (LUCENE-6819) and that indices record the version that was used to create them (for backward compatibility, LUCENE-7703), we can look into storing the length normalization factor more efficiently.
