For example, that could cause Lucene to loop endlessly while trying to index pages, among other things. This is caused by the Lucene migration to 4.0 (see [[XWIKI-8404>>http://jira.xwiki.org/browse/XWIKI-8404]]).

192	192	* Changes in the experimental Solr implementation
193	193	** The ##xwiki.properties## file now contains solr specific configuration, please make sure to merge it with your own. If you were previously using the ##search.solr.home## property to specify your own index directory, you need to use the new ##solr.embedded.home## property, as specified in the xwiki.properties file.
194	194	** The Solr index and configuration files have suffered major changes. When upgrading, you need to delete the ##<permanentDirectory>/solr## directory so that Solr can reinitialize it with the new configuration and index structure. Also, a reindexation is obviously required.
