elasticsearch _tasks 获取描述信息

貌似api里不支持那么多参数，一眼看过去只有这些参数可以用
detailed，nodes，actions，parent_task_id，wait_for_completion，timeout
 
所以估计你得自己写代码过滤description了。
 
在`org.elasticsearch.rest.action.admin.cluster.RestListTasksAction`里面

public static ListTasksRequest generateListTasksRequest(RestRequest request) {

        boolean detailed = request.paramAsBoolean("detailed", false);

        String[] nodes = Strings.splitStringByCommaToArray(request.param("nodes"));

        String[] actions = Strings.splitStringByCommaToArray(request.param("actions"));

        TaskId parentTaskId = new TaskId(request.param("parent_task_id"));

        boolean waitForCompletion = request.paramAsBoolean("wait_for_completion", false);

        TimeValue timeout = request.paramAsTime("timeout", null);



        ListTasksRequest listTasksRequest = new ListTasksRequest();

        listTasksRequest.setNodes(nodes);

        listTasksRequest.setDetailed(detailed);

        listTasksRequest.setActions(actions);

        listTasksRequest.setParentTaskId(parentTaskId);

        listTasksRequest.setWaitForCompletion(waitForCompletion);

        listTasksRequest.setTimeout(timeout);

        return listTasksRequest;

    }

主要考虑有多个批量更新时，我能根据指定的索引名过滤出来需要的那个 task
