[Zope] problem in zcatlog indexing

[Jianping Zhu]

I am following 
http://www.zope.org/Documentation/Books/ZopeBook/current/SearchingZCatalog.stx
to learn how to use zcatlog. and having some problem.

when i try to produce "Figure 9-3 Managing indexes" I got different 
thing:
instead of having
"ZCatlog at /AnimalTracker"
I got "ZCatalogIndex at  /AnimalTracker" and there are three tabs: undo, 
ownership security. and i can not difine index. 

How can i fix this problem and define index correctly?

Thanks
