[Zope3-Users] Beyond ICatalog.searchResults

[Mohsen Moeeni]

Hi;

Looking at ICatalog interface, I could not figure out
how can I request some simple and common operations
from my catalog.

- Sorting on a field index.

- Returning the first N-th results (Hopefully without
  awakening all catalog records - if that makes any sense)

- Defining an index which indexes an objects interfaces
   i.e the output of interface.implemntedBy(ob)

Cheers,
Mohsen,
