Well, the concept to reduce the number of results to a definitive list of categories is a good one. But it leads to some mistakes. First, it searches in databases such as Wikipedia. You cannot find a bigger fan of Wikipedia than me, but still it’s not suitable for such a search engine.
Second, sometimes there are strange things in the results. Only one example below. It seems to suggest that a possible treatment for diabetes is mouse. Of course, it just found articles mentioning mouse models in the research of diabetes treatments, but it cannot deal with the information properly.
