Although I can state that the user's minimal > config/schema are not very useful, Solr should not blow up without a useful > error message, and in this case, I think it should have worked, only emitting > a WARN message and assuming a default name. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
