Have you tried Ctrl+s? It lets you do simple matching, but only selects matching items.
There might be some programs out there that can filter the way you want, and you could create a custom action for it or bind it to a key. For example, since Thunar has no search function, Fedora Xfce ships with Catfish by default (available in most distros).
