Doh, typo! That should read
/a.*?c.*d/;
BTW, your RE should have a ``*'' as well:
/x.*?y/
Maybe, it depends on exactly what he was trying to get.
The first 3 character match where x and y are the first and third character respectivly, then x.y is exactly what you want. The smallest set of characters that have x and y as boundry values? Then your x.*?y is correct. The smallest set of characters that have x and y as boundries and have at least one character in between them? x.+?y is needed.
