To correct myself, the selected Similarity class can have a computeNorm
method that calculates the "norm" value that will be stored in the index
when the document is indexed, so changing the Similarity class will require
reindexing if the implementation of the computeNorm method is different.

Yes, if the replacing similarity has a different implementation on norms,
you should reindex or gradually update all documents within decent time.

How about SweetSpotSimilarity? Length norm is saved at index time?

The similarity class is only invoked at query time, so it doesn't

Hi - no you don't have to, although maybe if you changed on how norms are
encoded.
