Sorry. From the CHANGES for 1.3:
{quote}
The Porter snowball based stemmers in Lucene were updated (LUCENE-1142),
and are not guaranteed to be backward compatible at the index level
(the stem of certain words may have changed). Re-indexing is recommended.
{/quote}
Would have been nice to leave a back compat out, but I didn't see the
discussion around that, so I'm sure they did their best given the facts.
Be careful about reading the CHANGES file before upgrading Solr is my best
advice.
