I'm trying to search for a date that is greater than `DateTime.MinValue,` but elastic throws search\_phase\_execution\_exception. When I create `var d = DateMath.Anchored(DateTime.MinValue)` , `d.Self = null and d.ToString()` returns `String.Empty`. I do not observe this behavior with other dates, f.e. with `DateTime.MaxValue`.

```
 "range": {
                  "eventDateUtc": {
                    "gte": "0001-01-01T00:00:00"
                  }
                }

```

How can I make this filter using Nest? Elasticsearch can search dates that are greater than DateTime.MinValue.

I am using Nest 6.0.0 and Elastic 6.2.0

Why isValid is defined in this way?
