title: oData navigation vs filtering
body: <p>When using a navigation:
  <a href="http://services.odata.org/V4/Northwind/Northwind.svc/Suppliers(1)/Products" rel="nofollow noreferrer">http://services.odata.org/V4/Northwind/Northwind.svc/Suppliers(1)/Products</a>
  or filtering: <a href="http://services.odata.org/V4/Northwind/Northwind.svc/Products?$filter=SupplierID%20eq%201" rel="nofollow noreferrer">http://services.odata.org/V4/Northwind/Northwind.svc/Products?$filter=SupplierID eq 1</a></p>
  
  <p>I will get exactly the same results so products belonging to the supplier "1". So when and why should I use navigation and when filtering?</p>
