Select multiple CCK per facet

Hi

It seems that the multiple terms problem was resolve http://drupal.org/node/173524, but the same issue is with the handling of multiple answers per CCK field. E.g.
CCK field cars: (multiple choices allowed)
[x]van
[x]sedan
[x]cabrio

Now in the present facet configuration no matter that multiple choices are available the search will always restrict the choice to one of the answers.

Actually, I'm not quite sure if I should post the issue here or in the CCK facet module.
Cheers
