Why doesn't '??' run help.search() when using ESS?

Question

On my windows machine at work, when I type ??topic in the R terminal using ESS, I don't get the expected result of help.search(topic), instead I get a new buffer titled *help[R](?topic)*, with contents:

No documentation for '?topic' in specified packages and libraries:
you could try '???topic'

My google-fu has failed me so far in finding the cause, but I'm sure someone else has sorted this out by now. What do I need to change in my configuration to make this work?

Answer 1

This has been sorted out for quite some time in ESS. Try upgrading.

With the new version of ESS you can get the same behavior with C-c C-d C-a which stands for apropos.
