I went through the solr-ref-guide. I got a brief idea on how it works, But I can't help to think as to why I am unable to create a core through web UI ? Does it have any dependency on SolrCloud ? If I am planning to run an standalone instance do I need to create core's only through the command line and with 'solr' user privileges ? Please advise.
