RestHighLevelClient批量刪除滿足某些條件的數據

這個可以通過DeleteByQueryRequest來實現，實例代碼如下

	/**
	 * 批量刪除文檔
	 * @throws IOException
	 */
	@Test
	public void deleteByQueryRequest() throws IOException {
		DeleteByQueryRequest request = new DeleteByQueryRequest("sub_bank1031");
		request.setDocTypes("sub_bank");
		request.setQuery(new TermQueryBuilder("unionNumber", "104663451012"));
		request.setSize(1);
		BulkByScrollResponse resp = highLevelClient.deleteByQuery(request, RequestOptions.DEFAULT);
		println(resp);
	}
