I got a nested field in the doc in this form and want to write a query applying the boosting on this field:

Previously the nested field structure was something like this:

```
...
"my_nested_obj": {
    "project-type": [
      "skill-level": [
        {
          "name": "Intermediate",
          "value": "63897"
        }
      ],
      "room": [
      {
        "name": "Outdoor",
        "value": "19246"
      }
    ]
  }.......

```

and I could apply boosting on the field like this:

```
...
"query": {
    "filtered": {
      "query": {
        "filtered": {
          "query": {
            "multi_match": {
              "query": "some query",
              "fields": [
                "title^3",
                "excerpt^2",
                "my_nested_obj.skill-level.name^3"
              ],
              "operator": "and",
              "type": "cross_fields"
            }
          },
....

```

The nested field structure reformatted and looks like this:

```
"my_nested_obj": [
        {
          "name": "Intermediate",
          "type": "skill-level",
          "value": "63897"
        },
        {
          "name": "Outdoor",
          "type": "room",
          "value": "19246"
        }
      ]....

```

How do I go about applying the boosting on the nested field and rewrite the above query?

Thanks!
