[Zope-dev] ZCatalog searching for missing values

[Bjorn Stabell]

Hi all,

We've installed Kavio's CatalogQuery product and are very happy with it.
Haven't looked at the ZOQLMethod from iuveno yet, but both look like
great steps in the right direction.

I have one question: is it possible using a normal catalog query or
Kavio's catalog query to check if a value is not set?  The
representation returned is Missing.Value, but I seem to be unable to
say, e.g, 'Description =3D=3D Missing.Value' etc.  How hard is it to add
such functionality?

Bye,
