(1) I will add in the functionality to show nearby hospitals without average wait times. It seems easy enough and very useful without search functionality. FWIW, if the government doesn't report wait times, I default to the average ER wait time for your state. If there is no average ER wait time for your state, then I use the national ER wait time reported by the gov. May I ask where in the country you are located?
One thing to note, I explicitly query for hospitals within a 10 mile radius. I figure if it's more than 10 miles out, it's probably not worth the drive. Maybe I should rethink that assumption...
(2) The search functionality is definitely coming in an update. I've heard that it would be useful from numerous people.
