While trying to upgrade from ES 1.2.2 to 1.3.4, we have noticed that since Smart Chinese Analysis plugin release 2.3.0 _smartcn\_sentence_ and _smarcn\_word_ have been deprecated as a result of changes in Lucene. At the moment we do have dozens of indices which already use those classes in their mappings and are trying to figure out how to proceed with the upgrade. Is there a best / preferred strategy to do that? Thanks, Mateusz -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
