@ -29,6 +29,10 @@ IMPORTANT UPGRADE NOTE: In a master/slave configuration, all searchers/slaves
should be upgraded before the master! If the master were to be updated
first, the older searchers would not be able to read the new index format.
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.
Older Apache Solr installations can be upgraded by replacing
the relevant war file with the new version. No changes to configuration
files should be needed.
