[Zope] Multiple ZCatalogs and automatic reindexing

[Milos Prudek]

I'd like to have several searchable types in ZCatalog. Let's say I have
ZClass Z1, Z2 and Z3. I need to catalog them SEPARATELY. 

1. Do I need several ZCatalogs?

2. Do I need Zope 2.4.1?

3. For CatalogAware automatically reindexing, is it still neccessary to
give the catalog the name "Catalog", and place it in root folder?

The third question puzzles me the most, because it seems to prevent me
from creating several ZCatalogs, if I need them reindexed automatically.
