hits returns me the found id, score, type... but not the other fields

Hi

I am just starting with ElasticSearch and maybe it is something obvious but I can't figure it out why I can't get all the info with my query.

I used the TypeComposer example to create my own and then I query with:

```
{
searchActivities(
query: {
multi_match: {
query: "blur",
fields: ["title", "description"]
}
}
){
hits
}
}
```

But I get only:

```
"searchActivities": {
"hits": [
{
"_index": "myfirstindex",
"_type": "activities",
"_id": "2",
"_score": 0.2876821
}
]
}
```

With the other demo "API Proxy" I could get the other info, but I saw that every ES method was available, including creation or deletion of indices and I want this /graphql endpoint to be public.

Can someone point me in the right direction?

Thanks
