[Zope] Help on ZCatalog

[Willie Peloquin]

Hi,

I have created a ZClass and would like to use a ZCatalog, I have not been
able to find any tutorial or an example to make this work.

For example, I want to create a ZClass to contain CD objects, as in the
tutorial. I now want to build a search screen to find all my Jimmy Buffett
CD's. I use ZCatalog for that. I was able to set up a ZCatalog and find the
CD instances, but that is as far as I could get, I don't understand how to
search for ARTISTNAME = *, or something similar.

Thanks,

Willie
