advanced search include subcollections

variable

I have a collection called (creatively) "GIANT MIX" which I am trying to organise. It has a few subcollections.

Advanced search does not show these subcollections when using advanced search to search by collection.

Is there a way to use 'advanced search' to search a collection and all subcollections?
