Vista - Creating a search folder like "Files updated this week"

Hi,
I want to create a virtual folder like this and place it along with my other
folders (Not into the dedicated C:\Users\<User Name>\Searches folder.
The idea is the virtual folder should automatically populate the contents
based on the current directory.
That's if I place it in D:\Hello\World\Program1 it should show me the files
that are modified within this folder. Similarly if I place it in
D:\Hello\World\Program2 it should show me the files that are modified within
this folder.
I tried editing the .ms file directly, but the problem I face is that, I'm
not able to give relative path (in this case, current working directory "./")
to the search folder.

The problem with absolute path is that, I've to change the search folder
whenever I move my folders around.

Any ideas on how to circumvent this problem?
