I just realized that I in this previous post forgot to share my “search page provider” – a page provider that searches for the newest pages in a specific page type using Johan Olofssons LINQ to PageData – and returns the results as children.

It’s a little bit special because it in itself does not actually create any pages – it just returns links to other already existing pages.
