Hi,  
currently working on a vega viz and right now i'm stuck on how to proceed...  
My use case is to be able to lookup on an index where one field of a given document is an array of json.  
Have a look of the code below:

```
{
  "$schema": "https://vega.github.io/schema/vega/v3.json",
  "width": 960,
  "height": 500,
  "autosize": "none",

  "data": [
    {
      "name": "data1",
      "values": [
        {
          "list": [
            {"id": 1, "text": "ok1"},
            {"id": 2, "text": "ok2"},
            {"id": 3, "text": "ok3"}
          ]
      }
   ],
  "format": { "property": "list" },
  "transform": [

    ]
  },
  {
   "name": "data2",
   "values": [
     {"trackId": 1, "ok": 1},
     {"trackId": 2, "ok": 2},
     {"trackId": 3, "ok": 3}
    ],
   "transform": [
      {
        "type": "lookup",
       "from": "data1",
       "key": "list.id",
       "fields": ["trackId"],
       "as": ["obj"]
      }
    ]
}
]
}
```

@nyuriks can you please take a look? I am pretty sure this is not possible yet?

Thanks,
