But the Analyzers can be (we can have the old stemmer available also),
and if we create an analyzers/sv or whatever that uses the
SmartSwedishStemmer or whatever its named, its not a back compat break
as long as you can still use SnowballAnalyzer("Swedish") and get the
old one, right?
For I think a first example of improving analyzers with Version, check
out the modifications to CzechAnalyzer, with that one we added a
stemmer where there was not one before, but the stemming only takes
place with Version >= 3.1 by default. In my opinion we should exploit
Version to improve analyzers, based upon relevance testing or
published relevance results if at all possible, of course.
