Hi, ``` I am new to elasticsearch. I am using JAVA Api to establish connection with ES. ``` public void createIndex(final String index) { getClient().admin().indices().prepareCreate(index).execute().actionGet(); } public void createLocalCluster(final String clusterName) { NodeBuilder builder = NodeBuilder.nodeBuilder(); Settings settings = ImmutableSettings.settingsBuilder() .put("gateway.type", "none") .put("cluster.name", clusterName) .build(); builder.settings(settings).local(false).data(true); this.node = builder.node(); this.client = node.client(); } ``` public boolean existsIndex(final String index) { IndicesExistsResponse response = getClient().admin().indices().prepareExists(index).execute().actionGet(); return response.isExists(); } ``` public void openIndex(String name){ getClient().admin().indices().prepareOpen(name).execute().actionGet(); } createLocalCluster("cerES"); createIndex("news"); System.out.println(existsIndex("news")); When i execute the above java code iam getting "true" response. But when i close the java program and start the program again with the following code: openIndex("news"); It is throwing IndexMissingException.But i can see the news index in Data folder of eclipse. So how i retreive data from the node previously?. Is it lost? or am i wrong somewhere? ---

Use gateway type "local" instead of "none", then your index persists across cluster restarts.
