I've been following recent discussion about relations in Zope. Both
intrinsic and extrinsic relationships.
For the following question lets assume we have a IClient and an IOrder
content types and the IOrder schema has a IClient attribute called 'client'.
Reading previous messages to this list I understand that's the best way
to model this kind of intrinsic relationship between an Order and a Client.
Now the question: using a Catalog, what should I do to answer these kind
- Give me all orders whose client's name starts with 'John'
- Give me all orders whose client's age is between 20 and 30
- Give me all orders for a certain client
I guess I need to use a special kind of FieldIndex for objects but I'm
new to the Catalog land and I'm pretty much lost.
Any help, examples or pointers to detailed doc are greatly appreciated :-)
