Question about Display Suite Search Results--is it possible to sort them in descending order?

I'm using Display Suite search to create search result pages. It works very well--except for one thing: the results seem to be random.

Is there a way to sort them in descending order? I read that it's possible to do this using a view block, but haven't seen any documentation or tutorials to accomplish this.

We're using Drupal 7.

Thanks in advance for any help!
