I create a mapping has three types(`app`,`group`,`productline`).`app`'s parent is `group`,`group`'s parent is `productline`.

Here are my query dsl(search for app type):

```
    {
        "has_parent": {
            "query": {
                "bool": {
                    "filter": [
                        {
                            "has_parent": {
                                "query": {
                                    "bool": {}
                                },
                                "inner_hits": {},
                                "type": "productline"
                            }
                        }
                    ]
                }
            },
            "inner_hits": {},
            "type": "group"
        }
    }

```

I find `productline`'s `inner_hits` always empty,but `productline` does exist data,How i to get all `parent`'s `inner_hits` data?
