Who do child items and search results share the same window?

[lascasas]

This is a design aspect of Ultra Recall I've never understood and wonder if people here can explain it to me:

Why do child items and search results share the same window?

I ask because sometimes I want the search results to persist for a while so I can use of the results for assigning items, flagging, etc., but if I click on a folder, the search results are replaced by the child items for that folder.

Why? What's the logic of that? How are child items and search results related?
