That seems sweet! One conf dir, many data-dirs = perfect. Some short questions
* How and where do one configure each core to have separate data vs instancedirs ? Still manually in solr.xml or by using the coreadminhandler ? * How do one use the CoreAdminHandler ? (Google gives me only refs to the javadoc or nabble) * If one perform the changes through CoreAdminHandler then where are the changes persisted ? solr.xml ?
