I am making a collection of Municipal Acts with a simple and advanced
search. I've asigned a metadata category to all them but there is a problem
because a few documents belongs to more than one category.

The exploration classificator I've created is the next:

classify Hierarchy -metadata dc.T?tulo -sort dc.Title -buttonname "Orden
alfab?tico"

My question is "How can I assign more than one value to each document?".

For example, there are created 3 Categories: Buildings, Places and
Agriculture, and there is a documents which talks about Agriculture and
Places, Do I have to make a duplicate of the document or can be another
possibility?

Thank you
