elasticsearch 刪除 新增 修改文檔後不能立即生效

場景：頁面刪除某條記錄，刪除完成後系統會立即刷新列表頁，結果刪除的還在列表頁顯示，再次點擊查詢按鈕，被刪除的數據纔會消失

嘗試Thread.sleep(1000); 可以解決，但是不友好

DeleteRequest deleteRequest = new DeleteRequest(indexName,id);
deleteRequest.setRefreshPolicy(WriteRequest.RefreshPolicy.IMMEDIATE);
client.delete(deleteRequest, RequestOptions.DEFAULT);

刪除時增加刷新策略，立即刷新即可，一定要在client執行前設置

deleteRequest.setRefreshPolicy(WriteRequest.RefreshPolicy.IMMEDIATE);

參考官方api
