GMail search improvement request

Advance the search functionality, so it is as good as google.co.uk. Including "did you mean" and other neat additions. For instance, I type "chamnix" and "No messages matched your search", even "broadening my search" didn't pick up on any with the correct Chamonix spelling. Using the "Advanced" search doesn't come up with any either.

The search is just too basic for my needs presently! ;)
