"Creations by Media Molecule" should search for all creations, not just collections

I find it quite difficult to figure out which route through the Mm collections I should be taking when looking for a particular thing, especially for sound effects. I was so happy a "creations by Mm" search was added! But unfortunately it doesn't actually search all creations by Mm; only collections. And only the top level collections, at that.

If this searched the actual assets also, this would be super useful. And make it infinitely easier to find assets by Mm. This is especially good for audio, because it doesn't cost any download time for the player when we use them. But only if you can navigate through the collections well enough to find what you need.

Please adjust this feature to allow us to search for any Mm creation.
