I want to be able to have someone type into the little white box in the corner of the screen and have it match dc:source as well as its current sources, when it shows file suggestions before user submits search. I do not have Studio. Thank you! ...

I am trying to update the simple search to return results that match the defaults, as well as to pull from dc:source field. What is the proper format of a contribution xml extension to do such a thing?
