For more specific searches on global site managers, you can use the apidoc 
apis. They implement a lot of the searches that are commonly interesting:

>>> from zope.app.apidoc import presentation
>>> for reg in presentation.getViews(IFolder):
...    print reg.required, reg.provided, reg.factory, reg.name

There are a lot more helpful functions there and they are all well-documented.
