Great, you're ahead of the game then.

No, there isn't. What you are asking for is more like Apple or Microsoft's
new search engines, Spotlight, and WinFS respectively, that keep databases
of what is on your local hard disk so you can perform a quick
search. There is no way to search AFS cells like searching a local hard
drive, other than to do a bute force search for every file and directory.

AFS is a network file system. You use it to store files on the network, as
opposed to your local disk. Once stored there, you can retrieve the file
later by remounting the same AFS cell and traversing its subdirectories to
the point where the file is at. You need to remember that path, just like
you remember how to type in a web address. What makes AFS different than
the web is that AFS can be used directly by your OS applications when they
need to open a file by using any of the traditional "file open" OS API
calls. You don't have to go "though" a web server to get to a file. You
can use "VI" to edit a file right out of AFS. You can't do that with the
web. There are probably several thousands of terrabytes of on-line data
stored in AFS.
People who run AFS cells do so because they need an enterprise wide common
location for infrastructure data. AFS isn't an "archive" as much as it is
an active on-line "data repository". The word "archive" to me seems to
imply "backup". AFS "can" be used to backup user data, but that isn't its
primary purpose. Understanding the difference between what AFS is meant
for and what the Web is meant for is critical. They are not the same beast
and definitely serve different functions. Also remember that the web
typically serves "public" data verses AFS which is used to access an
organizations internal private data as well as public.
Some people run web servers "on top" of AFS. That means when you fetch a
web page with your web browser, the file is actually being pulled out of
AFS by the web server and sent to you. Our site does that.
I believe what you are looking for might be more akin to the old "archie"
UNIX utility for searching for files on a host. Don't be so quick to
dismiss the need for AFS. You are asking to do something that AFS doesn't
have a functional design for. Apples are not oranges.
