Path indexes are unable to do that.

They have the property:

  When an object with path "somepath/id" is a hit than any 
  object with path "somepath/anotherpath" is also a hit.

  You are therefore unable to restrict the depth of the hits
  (to the root folder in your case).

In your case, you may directly use "folder.ContentValues(['News'])"
(or similar; I am not sure about spelling).


An alternative would be to enhance PathIndex with a "depth" parameter
which allows to restrict the depth of hits.
