If field value is empty how can we avoid those in the Query.Filter issue

We have "NewDetailPage" and it has an 'asset type' field. Asset type field is ContentReference type.

Now we are showing two kinds of assets in the find results by following the below approach.

query = query.FilterByExactTypes(new List<Type> { typeof(NewsroomDetailPage) });

query = query.Filter(x => !(x as NewsroomDetailPage).Asset.Match(new ContentReference(22))); // news releases

query = query.Filter(x => !(x as NewsroomDetailPage).Asset.Match(new ContentReference(9987))); //videos

But how can we exclude the if the Asset Type field was empty?

If it's empty I'd imagine it'll be ContentReference.Empty so I'd suggest writing and exclude filter for any that match that.

query = query.Filter(x => !(x as NewsroomDetailPage).Asset.Match(ContentReference.Empty)); should work as Scott suggested

or you can write something like

public static FilterExpression<ContentReference> IsEmpty(this ContentReference value)
{
return new FilterExpression<ContentReference>(x => ContentReference.IsNullOrEmpty(x));
}
