Sorry for the delay - I've been trying to puzzle over this some more.

The code looks like

     server.add(docs);
     server.commit();
     server.optimize();

I'm seeing which would seem to indicate that both a commit and an 
optimize are happening and that a new searcher is getting opened.

documentCache{lookups=0,hits=0,hitratio=0.00,inserts=10,evictions=0,size=10,warmupTime=0,cumulative_lookups=0,cumulative_hits=0,cumulative_hitratio=0.00,cumulative_inserts=0,cumulative_evictions=0}

But I still the same result.


We ended up going a different route anyway but I'm still slightly 
confused. For what it's worth - the code for instantiating the server is

  SolrConfig solrConfig = new SolrConfig(CONFIG_PATH,"solrconfig.xml",null);
  IndexSchema indexSchema = new IndexSchema(solrConfig,"schema.xml",null);
  SolrResourceLoader resource = new SolrResourceLoader
               (SolrResourceLoader.locateInstanceDir())  

  CoreContainer container = new CoreContainer(resource);
  CoreDescriptor dcore = new CoreDescriptor(container, "",
    solrConfig.getResourceLoader().getInstanceDir());
            dcore.setConfigName(solrConfig.getResourceName());
            dcore.setSchemaName(indexSchema.getResourceName());

  core = new SolrCore(null, DATA_PATH, solrConfig, indexSchema, dcore);
  container.register("", core, false);
  server = new EmbeddedSolrServer(container, "");

Thanks,
