Adrien Grand updated LUCENE-7730:
---------------------------------
Attachment: LUCENE-7730.patch
Here is an updated patch. I tried moving TFIDFSimilarity and ClassicSimilarity
to misc yesterday but gave up due to how MLT and some values sources depend on
it. This new patch removes the ability to customize the norms encoding in
TFIDFSimilarity and makes it compatible again with other similarities (so I
added it back to Similarity randomization).
> Better encode length normalization in similarities

> 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.
