HI Solr-3.1 version usage the the latest version of Lucene jars so if you are planning to Upgrade then it is necessary to Re index all the content with Solr3.1 version. Not re-indexing will possibly cause of index corruption because newer version of lucene will create indexes in Newer version which is backward compatible for read only. setting <luceneMatchVersion>LUCENE_31</luceneMatchVersion> is not enough because it will not get the lucene 3.1 jar automatically. ----- Thanx: Grijesh www.gettinhahead.co.in -- View this message in context: http://lucene.472066.n3.nabble.com/Solr-3-1-Upgrade-Reindex-necessary-tp2919679p2922645.html Sent from the Solr - User mailing list archive at Nabble.com.
