Using elasticsearch, I'm trying to add my hit results into a list after they are returned, like this:

```auto
var lstModels = new SearchResult<mdl.Event>();

var searchResponse = Event.client.Search<mdl.Event>(s => s
                    .Query(q => q
                        .QueryString(qs => qs
                            .Query(search.Text))
                        && q
                        .DateRange(r => r
                            .Field(f => f.CreatedTimeStamp)
                            .GreaterThanOrEquals(search.From)
                            .LessThanOrEquals(search.To))));
                lstModels.AddItems(searchResponse.Hits);

```

However I am getting an error saying that my types are incompatible.

```auto
cannot convert from 'System.Collections.Generic.IReadOnlyCollection<Nest.IHit<Event>>' to 'System.Collections.Generic.IEnumerable<Event>'

```

Why are my hits returning as part of the Read Only Collection? Is there a way to change this so that they are usable?
