[Zope] multi-column sort with ZCatalog

[Mark Nenadov]

Hello all,

I have a simple ZCatalog query with a sort_on and sort_order being
passed to it.

Is there any way I can do the sort on multiple columns? This seems like
an important feature. I've heard that is not possible, but I'm wondering
if I am just missing something/getting wrong info.

I'm already looking into the Generic Sort External Method, but I'm
wondering if there is some other way to do this?

Thanks,
~Mark
