elasticsearch批量删除请求成功，但不起作用

Question

我正在尝试使用BulkProcessor执行批量删除请求，初始化代码如下：

BulkProcessor bulkProcessor = BulkProcessor.builder(client, new BulkProcessor.Listener() {
            @Override
            public void beforeBulk(long executionId, BulkRequest request) {
                log.warn("executionId:" + executionId + " bulk start => numberOfActions:" + request.numberOfActions() + " size:" + request.estimatedSizeInBytes());
            }

            @Override
            public void afterBulk(long executionId, BulkRequest request, BulkResponse response) {
                log.warn("executionId:" + executionId + " bulk end => tookInMillis:" + response.getTookInMillis());
                log.warn("executionId:" + executionId + " bulk end => response:" + JSON.toJSONString(response));
            }

            @Override
            public void afterBulk(long executionId, BulkRequest request, Throwable failure) {
                log.warn("executionId:" + executionId + " bulk executed occur error:", failure);
            }
        }).setBulkActions(500).setBulkSize(new ByteSizeValue(14, ByteSizeUnit.MB)).setConcurrentRequests(1).build(); 

//search ids to delete
List<String> ids = searchByCondition(index,type,start,end);     //ids.size() = 500
//call bulk
    for(String id : ids){
        DeleteRequest deleteRequest = new DeleteRequest(index, type, id);
        bulkProcessor.add(deleteRequest);
    }

在请求后，es中没有记录被删除。而且我得到的处理结果日志如下：
