With embedded solr (1.3.0) sometime a SolrException happens. I don't understand why : I have not been able to find a scenario.
org.apache.solr.common.SolrException: No such core: core0 at org.apache.solr.client.solrj.embedded.EmbeddedSolrServer.request(EmbeddedSolrServer.java:112) at org.apache.solr.client.solrj.request.UpdateRequest.process(UpdateRequest.java:217) at org.apache.solr.client.solrj.SolrServer.deleteById(SolrServer.java:97) Regards JF
