[pmwiki-users] pagelist/search -- getting all pages where a page text variable matches a certain value

[tamouse mailing lists]

I've been going through the documentation and the cookbook and I can't
find an answer for this.

Is is possible, using either pagelist or search to retrieve a set of
pages that contain a page text variable that matches a certain value?

For example, if I have several pages that contain:

    Parent:Desserts

I'd like to get the list of pages where $:Parent=Desserts. Is this possible?
