Issue querying for dates

Oh also here's the mapping for that field:

    "created_at" : {
      "omit_term_freq_and_positions" : true,
      "index_name" : "created_at",
      "index" : "not_analyzed",
      "omit_norms" : true,
      "store" : "no",
      "boost" : 1.0,
      "format" : "dateOptionalTime",
      "precision_step" : 4,
      "term_vector" : "no",
      "type" : "date"
    },

Hi, I'm having an issue querying for dates, and it's probably me using
the query dsl wrong, but I can't figure out what the problem is.

This query works:
{
"query":{
"range":{
"created_at":{
"from":"2010-08-26T20:41:52Z",
"to":"2010-08-26T20:41:52Z"
}
}
}

}

but this query doesn't:
{
"query":{
"field":{
"created_at":"2010-08-26T20:41:52Z"
}
}

}

It throws this exception:gist:552231 · GitHub

I'm using 0.9.0 for this test.

Is there something wrong here?
