Asp.net Search function issues

I have a simple search function that allows me to search for certain words from different tables. This is annoying as I feel there is a simple fix i'm not seeing here. Can someone assist? Thank you in advance.

ViewModel

IEnumerable<Owner> Owners {get; set;}
IEnumerable<Car> Cars {get; set;}

Search Method

public IEnumerable<ViewModel> Search(string search)
 {
   ViewModel searchVM = new ViewModel();
return searchVM.Owner.Where(o => o.Name.Contains(search)) ||

searchVM.Cars.Where(c => c.Model.Contains(search));

}

Error

Operator ‘||’ cannot be applied to operands of type ‘IEnumerable<Owner>’ and

‘IEnumerable<Car>’
