Zope capabilities question

[Ben]

Hi all, wonder if anyone can give me some tips on this subject. 

I am attempting to build a portal which will allow the display of
information by keyword or subject, independently of the directory or
folder it is stored in. For example, say I had a several departments
in my company. One produces documents about cars, the other about
airplanes. These will sometimes have things in common. So, I want to
implement a system whereby when a user clicks on the 'tyres' section
all the relevant document metadata from each department appears on one
page. It should seem to the user like there is a seperate 'tyres'
section.

Sorry for the bad analogy; hope you see what I mean.

It is possible for a Zope solution to do this, or will I have to start
building in PHP or something similar?
