How to add another filter to Scald search? I have added new field to the Scald Image atom admin/structure/scaldwhich is called description and it is text area multiple rows. Now I want to have this field in the search to be shown at the below screen shot.

I tried to edit the field by checking MEE Enabled but I could not get it in the search.
The search is provided by a View called Scald Atoms.  Add the filters you want to that view.
