filtering by date in elasticsearch

Question

I'm Trying to search for all the items who have a field of date inside a range, and it fails (returns no results)

The query:

{
  "query": {
    "filtered": {
      "query": {
        "match_all": {}
      },
      "filter": {
        "range": {
          "last_updated": {
            "from": "2013-01-01 00:00:00"
          }
        }
      }
    }
  }
}

The mapping:

{
    "my_doctype": {
        "_timestamp": {
            "enabled": "true"
        },
        "properties": {
            "cards": {
                "type": "integer"
            },
            "last_updated": {
                "type": "date",
                "format": "yyyy-MM-dd HH:mm:ss"
            }
        }
    }
}

results in:

 {
        took: 1
        timed_out: false
        _shards: {
            total: 1
            successful: 1
            failed: 0
        }
        hits: {
            total: 0
            max_score: null
            hits: [ ]
        }
    }

The same query filtered by a range for an integer field("cards") with a numeric value works fine. Changing the date to a very early start (1900-01-01 00:00:00) also shows no results.

What am I doing wrong?

BTW, I know I have the _timestamp enabled in the mapping, but that is not the field I am filtering by.

Seems to be working fine to me:

curl -XPUT localhost:9200/test -d '{
    "settings": {
        "index.number_of_shards": 1,
        "index.number_of_replicas": 0
    },
    "mappings": {
        "doc": {
            "_timestamp": {
                "enabled": "true"
            },
            "properties": {
                "cards": {
                    "type": "integer"
                },
                "last_updated": {
                    "type": "date",
                    "format": "yyyy-MM-dd HH:mm:ss"
                }

    }
