Change default search order for rank to newest?

Hi is there a way to change the default display order in searches from "rank" to "newest"?
As an example I have a "search by film type" menu here that works off keywords:
https://guy.smugmug.com/Walkabout-Film/Just-Film-/

But the results are always sorted by rank but newest would be much better for my needs.

Thanks.
