I have an object

```auto
    public class SomeObject
    {
       List<SomeType>
    }

```

There are several derived types of SomeType and populated in the list. However when i push this data into ES using [Nest.net](https://github.com/elastic/elasticsearch-net) it strips out the derived properties and only contains the SomeType values. is there a way around this?
