Parse error

[jmrichardson]

I am getting this error:

{
"reason": {
          "type": "parse_exception",
          "reason": "failed to parse date field [1420070400001] with format [dateOptionalTime]",
          "caused_by": {
            "type": "illegal_argument_exception",
            "reason": "Unrecognized chars at the end of [1420070400001]: [0001]"
          }

I can do a test filter using epoch only if I add the epoch_millis format:

GET _search
{
    "query": {
        "range" : {
            "file.last_modified" : {
                "gte" : "1420070400001",
                "format" : "epoch_millis"
            }
        }
    }
}
}

Is there a way to update the query to use format?

Thanks
