Elasticsearch - index only part of the object

Is it possible to index only some part of the object in elasticsearch?

Example:

$ curl -XPUT 'http://localhost:9200/test/item/1' -d '
{
    "record": {
        "city": "London",
        "contact": "Some person name"
    }
}

$ curl -XPUT 'http://localhost:9200/test/item/2' -d '
{
    "record": {
        "city": "London",
        "contact": { "phone": "some-phone-number", "name": "Other person's name" }
    }
}

$ curl -XPUT 'http://localhost:9200/test/item/3' -d '
{
    "record": {
        "city": "Oslo",
        "headquarters": { "phone": "some-other-phone-number", 
                          "address": "some address" }
    }
}

I want only city name to be searchable, all remaining part of the object I want to leave unindexed and completely arbitrary. For example some fields can change it's type from object to object. Is it possible to write mapping that allow such behaviour?

UPDATE

My final solution looks like this:

{
     "test": {
        "dynamic": "false",
        "properties": {
            "name": {
                "type": "string"
            }
        }
    }
}

I add "dynamic": "false" on the lowest level of my mapping and it works as expected.

You can achieve this by disabling dynamic mapping on entire type or just inner object record:

"mappings": {
    "doc": {
        "properties": {
            "record": {
                "type": "object",
                "properties": {
                    "city": {"type": "string"}
                },
                "dynamic": false
            }
        }
    }
}
