[Zope] How to list objects across different containers in Zope's tree?

[Ausum]

Few days ago there was this same question although remained unsolved.
This is the case for a news site: 

News objects are within section folders, within day folders, within
months, and within a year folder. Just like this, at the root:

http://zopesite:8080/2000/October/17/sports/newsobjectid_htm

If I were at, ie, root/2001/January/thislist_htm , how can I list(and
retrieve) sport news appeared from October 29th to November 10th in year
2000? Is it time to look for a database?

Thanks in advance,


Ausum
