How we separated parent from child was using Category. We put all the Parent spaces into one category class and then assigned the Childs to a different category which was descriptive of their space. Levels was another method we tested with fair results. Using the category method as an example, we created a space called Entertainment and assigned the category Interests. Entertainment is a parent space. All parent spaces are in the Interests category. Then we created Childs under Entertainment. For example, we created the child Music and put it under entertainment. When I go to Entertainment, I see on the screen all its child spaces. That is all how we did it by not solely relying on search.
