Actually, if I understand it myself :-) it acquires foobar because a method 
has no poperties, so it looks first in the innermost container, the folder 
TEST or TEST/2.

In that case, you start the acquisition with the document index_html (reread 
the HOWTO <http://www.zope.org/Members/michel/HowTos/DTMLMethodsandDocsHowTo>: 
the acquisition can start from a document or a folder, not from a method).

You started acquisition from index_html. Since it has no foobar, it looked 
into its own container, /TEST, then in root.

You can but the "problem" in your case, comes from the acquisition of an index_html document in a different folder. I suggest to add index_html documents in every folder *or* make index_html a method (this is what I use).
