Hmm. From the problems they identify, their proposed solution of adding Ajax controls to a moded search, in my opinion, utterly misses the point. Moded searches (and moded interfaces generally) have long been known to create usability problems. Rather than providing a search that works differently depending on the previously selected settings, it's better to let the user choose their options on the fly, so they don't have to remember to toggle off an old setting. Many of the problems identified are things that are pretty easy to fix, but every fix comes at a price. On our catalog we set the "advanced" search not to include the heading browse, so the problem identified in this article with people trying to apply bibliographic-level limits to heading-level indexes just doesn't occur. The downside is, most people don't find the heading browse ("Begins with ...") option when they do, in fact, want an exact title. It'll be interesting to see the findings when the researchers test their proposed interface.
