Alan Woodward commented on LUCENE-10312:
----------------------------------------
Hi, it looks like this adds the new PersianStemmer to all PersianAnalyzer
instances, but that will cause compatibility issues as somebody who indexed
using a PersianAnalyzer in 9.1 may find that they don't get hits any more when
searching using 9.2 because the results of their analysis chain would be
different. I think we need to add stemming as a configuration option that is
disabled by default, so that you can opt in to the new stemmer but we don't
break backwards compatibility.
