Using properties

Hi all,

I'm trying to list documents in a search, based on the country of the user that has logged on to the portal. Therefore I'm using the Search option set with predefined properties this is what I did:

-create a property called country (EN,DE,FR,NL, etc)

-create a search option set with predefined property: country(value=%ume_user_country%). I also tried %user.country% and a lot of variations, but it doesn't work.

-Is this possible?

-What should the values of the property country be restricted to?

-What is the correct statement?

I would also like to do this for the subscription property. same here:

-copied the cm_rnd_subscription property and made it indexable.

-created a search option set with predefined property: cm_rnd_subscription=????? Is this possible and how do I know the allowed values, is there any documentation available for these issues?

Thanks in advance and kind regards,

Barry
