If I were to put a `must` inside a `filter` like this:

```auto
"bool": {
  "filter": [
    {
      "bool": {
        "must": [
          ...
        ]
      }
    }
  ]
}

```

instead of another `filter` clause, does it open a [query context](https://www.elastic.co/guide/en/elasticsearch/reference/2.2/query-filter-context.html) whose scoring is thrown away later or does the top level filter context get inherited to the inner `bool` queries?
