when retrieving documents with NEST with this code:

> ```
> var result = elk.Search<FileBeatDto>(x => x
> .Index("filebeat-*")                
> .AllIndices()
> .Type(type)                               
> .Query(q => 
> q.Match(qs => qs.Field("fields.asset_tag").Query(asset_tag)) &&
> q.Match(qs => qs.Field("message").Query(filter))
> )
> .Take(lines)
> );
> 
> ```

I get documents but the timestamp is always null.

This is FilebeatDto:

> ```
> public class FileBeatDto
> {
> public DateTime timestamp { get; set; }
> public string datetime { get; set; }
> public DateTime received_at { get; set; }
> public int offset { get; set; }
> public string version { get; set; }
> public string input_type { get; set; }
> public int count { get; set; }
> public Beat beat { get; set; }
> public string host { get; set; }
> public string source { get; set; }
> public string message { get; set; }
> public string type { get; set; }
> public object fields { get; set; }
> public List<string> tags { get; set; }
> }
> 
> ```

Any idea why timestamp is null? I tried with @timestamp and timestamp.
