How to use oracle.ifs.search.ContextSearchSpecification.setMedia()

Question

The javadoc states that "The user can also specify the Media on which the Text Queries are to be performed".
How ?
The Media[] argument of this method is not documented and there seems to be no constructor for the class either.
I want to make a context query on content in one class + on description (or also content if that were impossible) in another class.

This allows a content search on description.
It uses the FreeForm SQL ability. It gets the score for the search of the related Content. I'm not sure if I can get the score for the description search.
