I wrote a BBC scope that uses departments. The root department is News, and there are many subdepartments, like World, Business, Nature, etc.
So, assume the user opens the Nature department and wants to find the article about "honey bees". They enter 'h', and only Nature articles with 'h' display, which seems correct. The PROBLEM: then they add 'o' (second letter in 'honey'), but now the honey be article does not display, instead only articles in News (the root department) display. Again, they cannot search for an article in a department other than root.
