Solr 4.2 implements a feature to proxy requests if the core not exists in node requested. https://issues.apache.org/jira/browse/SOLR-4210
Actually exists a bug in this mechanism https://issues.apache.org/jira/browse/SOLR-4584 Without the proxy feature, creating the cores using manually or on automatic way, you only can query the collection in nodes that have least 1 replica of the collection. If you have a solrCluster with 4 nodes and the collection only have 2 shards without replicas, then you can only query the collection in 50% of the cluster. (assuming that proxy request mechanism doesn't work properly) When I said to create manually the collection, you need to create manually all shards that form the collection and the replicas in the others nodes of the cluster. It takes work, but if you want have some control you need to pay the price. If it is possible that you can manage the name of shard with the collection API, the documentation doesn't say how. -- Yago Riveiro Sent with Sparrow (http://www.sparrowmailapp.com/?sig) On Tuesday, April 2, 2013 at 5:15 PM, Lukasz Kujawa wrote: > l
