The current way of allowing the omission of a core name in the URL is to name the core DEFAULT_CORE. While this functionality is great, and allows a multi-core setup to be back compat with existing URLs, if someone does want to also refer to the core by it's proper name, it looks pretty ugly. This also impacts SolrCloud, since the core name is used as the collection name by default (and a collection name of DEFAULT_CORE is... ugly).
So I'd propose that we either: 1) allow an optional flag in solr.xml to mark that any core is also the default core 2) rename DEFAULT_CORE to something nicer like "collection1" It seems like #1 would be preferable... thoughts? -Yonik http://www.lucidimagination.com
