Hi Shaun, you create the SolrServer using multicore by just adding the core to the URL. You don't need to add anything with SolrQuery.
URL url = new URL(new URL(solrBaseUrl), coreName); CommonsHttpSolrServer server = new CommonsHttpSolrServer(url); Concerning the "default" core thing - I wouldn't know about that.
