How do I sort Quick Search in descending order?

System

I currently have code to Quick Search and returns 100 assets at a given instant. I have a container of thousands of assets and they are all named by date (and other info) thus they are sorted in chronological order. However, I would like to return my 100 results in descending order of the name of the asset. Essentially I want to Quick Search the 100 newest records.

How do I do that?

Example of file names.
