Dear all,

I want to retrieve only "14" from this message

`3/03/0 EE 14 GFR 20 AAA XXXXX 50 3365.00`

this is my grok code

```
grok{
 match => {
        field1 => [
          "(?<number_extract>\d{0}\s\d{1,3}\s{1})"       
        ]         
      }
}

```

I would like to match just "14" first match

Best regards
