elasticsearch query not working on nested query with php

Question

I'm having some problems with a query, I have a nested document

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
                                        )

                                )

                        )

                )

        )

)

When I run a standard query with the elasticsearch php library

$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>';

I get a result. But when I change the query parameter to search foo

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

I get an exception being thrown

  "error": "SearchPhaseExecutionException[Failed to execute phase [query], all shards failed;

              ]]];
            nested: QueryParsingException[[holiday] [match] query does not support [foo]]; }]",
  "status": 400
}

Any ideas why the nested query is breaking?

If you use the default mapping, the data field has been dynamically mapped to type object (documentation here).

Consequently, to query on a sub-property of your object, you should use dot notation like this :

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