ドキュメントをエラスティック検索に挿入するための Java コード
Client client = new TransportClient().addTransportAddress(new InetSocketTransportAddress("127.0.0.1", 9300));
Map<String, Object> json = new HashMap<String, Object>();
json.put("user","dummy");
json.put("name","dumm");
IndexResponse indexResponse = client.prepareIndex("myindex", "mytype").setSource(json).execute().actionGet();
System.out.println(indexResponse.toString());
