I am following http://www.zope.org/Documentation/Books/ZopeBook/current/SearchingZCatalog.s... 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
