Sort by race of units?

[Kanaru]

When searching for a model, I usually look for certain races. For instance, a dwarf. If I search 'dwarf' into the search box, I find like 3 models. Of course, there are probably many more dwarf models, except they don't contain 'dwarf' in the name.

Having a way to sort by races, like wc3sear.ch, would be very helpful.
