It is fully searchable and really neat. If you’re a conference organizer looking for philosophers in your city who work on X, you can search the directory and come up with a list of such philosophers from underrepresented groups that fit the bill. If you’re on a hiring committee, and the usual suspects keep coming to mind but you’d like to do a more thorough search, you can pull up the directory and find all philosophers in the directory who work in a general AOS or even on a specific research topic. If you’re an editor looking for a list of possible candidates to invite to contribute to a volume or to referee a paper, the UPDirectory can help you.
This sounds like a really wonderful tool. Go check it out!

As many have pointed out at DN, this resource, however useful, is oblivious to the single most important cause of underrepresentation in philosophy: low socio-economic status.
