Search for "Solanum" and you'll see it offers links on the right side to all the custom databases in that genus. Moreover, in the results it shows a pretty powerfully ranked selection of popular tomato plants.

Similarly, search for "Abelia" and the first result is Edward Goucher followed by Kalaidoscope. These are, of course, the two most likely abelias the common gardener would be looking for.

Another example is Echinacea. Note that the popular ones appear at the top. At the bottom is the plants that nobody grows.

Contrast that with the old (current) search engine:

Note that the third result is a species plant that has zero images, zero comments and doesn't even have any data fields. It shouldn't be so prominent!
I'm feeling pretty good about my beta search and I think I'll launch it tomorrow.
