How to get results of inner hits in ongr?

[demianchuk]

Hi,

I have next simple exaple
$manager = $this->get('es.manager.user_index.auction_document');
$search = $manager->createSearch();
$hasParentQuery = new HasParentQuery(
'user_document',
new MatchAllQuery(),
["inner_hits" => new MatchAllQuery()]
);
$search->addQuery($hasParentQuery);
$result = $manager->execute($search);
dump($result);
die;

That gives me inner hits with query results.

DocumentIterator {#681 ▼
-aggregations: null
#documents: array:4 [▼
0 => array:8 [▼
"_index" => "user_index"
"_type" => "auction_document"
"_id" => "1847622"
"_score" => 1.0
"_parent" => "53247"
"_routing" => "53247"
"_source" => array:43 [▶]
"inner_hits" => array:1 [▼
"user_document" => array:1 [▶]
]
]
1 => array:8 [▶]
2 => array:8 [▶]
3 => array:8 [▶]
]
-count: 4
-converter: Converter {#205 ▶}
-manager: Manager {#840 ▶}
-managerConfig: array:6 [▶]
-scrollId: null
-scrollDuration: null
-key: 0
-aggregations: []
}

How can I get inner hits? Don't see any getter neither on result search object neither on document object
Does it exist?

Inner hits you can get through the raw iterator. It is too complicated to convert them to the objective representation. Not sure if I will ever add inner hits support to the DocumentIterator.
