Here is one example of why we think that Find Policy is a useful tool. We searched for "charter schools" in general Google, and on our Policy engine (which of course is also powered by Google, but customized). On the right you see the results from Find Policy. These get you to policy research much faster.
The Find Policy engine also seemed to return results from a nice diversity of institutions, as you can see when you enlarge the image. We will keep testing the engine, and post results.
