Very cool and extremely useful. First thoughts: The site is slow for me. There's no feedback indicating the system has captured user input. On my first visit, I immediately started typing random function names into the search box ('strlen', 'htmlentities', 'func_get_args', etc). I had no idea anything was going on and assumed that my search returned no results. It's only when I tabbed out for a few moments and tabbed back that I saw the site worked at all. When I saw the results, though, my reaction was something like "Wow, that's awesome."
