elasticsearch-java-restful-api常見問題

1、java-restful-api查詢所有索引名（_cat/index?v）

ClusterHealthRequest request = new ClusterHealthRequest();
ClusterHealthResponse response = myRestClient.cluster().health(request, RequestOptions.DEFAULT);
Set<String> indices = response.getIndices().keySet();
System.out.println(indices.toString());
