Erick Erickson resolved SOLR-12534. ----------------------------------- Resolution: Not A Bug This issue tracker is not a support portal. Please raise this question on the user's list at solr-u...@lucene.apache.org, see: (http://lucene.apache.org/solr/community.html#mailing-lists-irc) there are a _lot_ more people watching that list who may be able to help and you'll probably get responses much more quickly. If it's determined that this really is a code issue or enhancement to Solr and not a configuration/usage problem, we can raise a new JIRA or reopen this one. > Add Edge Labels for Graph exports to GraphML to allow imports to Gephi > ---------------------------------------------------------------------- > > Key: SOLR-12534 > URL: https://issues.apache.org/jira/browse/SOLR-12534 > Project: Solr > Issue Type: New Feature > Security Level: Public(Default Security Level.
