Hello! You can some find information about requirements of SolrCloud at http://wiki.apache.org/solr/SolrCloud . I don't know if _version_ is mentioned elsewhere.
As for Websolr - I'm afraid I can't say anything about the cause of those errors without seeing the exception. -- Regards, Rafał Kuć Sematext :: http://sematext.com/ :: Solr - Lucene - Nutch - ElasticSearch > On Thu, Oct 18, 2012 at 12:09 AM, Rafał Kuć <r....@solr.pl> wrote: >> Hello! >> >> The _version_ field is needed by some of Solr 4.0 functionality like >> transaction log or partial documents update.
