display suite search

I cannot get the 'highlight search word' feature to work, and wonder if I've got the HTML selector wrong or something else? Attaching a screenshot of my settings for this. Would be grateful for any suggestions! Thanks.

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!
