I want to use fields named `foo.ngram` & `foo.kuromoji` (`kuromoji` is Japanese morphological analyzer).

Setting like below does not work, saying `No type specified for field [foo]`.

```
{
    "mapping": {
        "properties": {
            "foo": {
                "fields": {
                    "ngram": {
                        "type": "text",
                        "analyzer": "ngram_analyzer"
                    },
                    "kuromoji": {
                        "type": "text",
                        "analyzer": "kuromoji_analyzer"
                    }
                }
            }
        }
    }
}

```

It seems I must set default type and analyzer to `foo` like this:

```
{
    "mapping": {
        "properties": {
            "foo": {
                "fields": {
                    "type": "text",
                    "analyzer": "kuromoji_analyzer",
                    "ngram": {
                        "type": "text",
                        "analyzer": "ngram_analyzer"
                    }
                }
            }
        }
    }
}

```

But I prefer the first one. Is there any way to do it?

Hey,

so you always need to have a default field mapping for the `foo` field itself, you cannot have `foo.ngram` and `foo.kuromoji` without having a mapping for `foo` as well.
