elasticsearch查询不适用于php的嵌套查询

Question

我在查询时遇到问题，我有一个嵌套的文档

Array
(
    [took] => 2
    [timed_out] => 
    [_shards] => Array
        (
            [total] => 5
            [successful] => 5
            [failed] => 0
        )

    [hits] => Array
        (
            [total] => 1
            [max_score] => 1
            [hits] => Array
                (
                    [0] => Array
                        (
                            [_index] => holiday
                            [_type] => holiday
                            [_id] => 31245
                            [_score] => 1
                            [_source] => Array
                                (
                                    [username] => john thomas
                                    [user] => 3
                                    [info] => test
                                    [phone] => 166872
                                    [data] => Array
                                        (
                                            [foo] => 28865
                                            [bar] => new test
                                        )

                                )

                        )

                )

        )

)

当我使用elasticsearch php库运行标准查询时

$client = new Elasticsearch\Client();

$params['index'] = 'holiday';
$params['type']  = 'holiday';
$params['body']['query']['match']['phone'] = '166872';

$results = $client->search($params);

echo '<pre>' , print_r($results) , '</pre>';

我得到结果。 但是当我更改查询参数以搜索foo

$params['body']['query']['match']['data']['foo'] = '28865';

我被抛出异常

              ]]];
            nested: QueryParsingException[[holiday] [match] query does not support [foo]]; }]",

}

有什么想法为什么嵌套查询会中断吗？

如果使用默认映射，则data字段已动态映射为类型object （ 此处的文档）。

因此，要查询object的子属性，应使用如下所示的点符号 ：

{
  "query": {
    "match": {
      "data.foo": "28865"
    }
  }  
}
