How do I prevent Autocomplete from searching for spaces?

How do I prevent Autocomplete from searching for spaces?

(which is documented at  http://docs.jquery.com/Plugins/Autocomplete)

I have a data set that includes:
Carl Anderson
Candy Ableton
Ric Arlo

If I type "c a" the only result is Ric Arlo, because it matches c space a.

I'd like to have it return all three items, because all three could be matches (or just have it return the top two only, because I never really need to search for spaces in my application).

Obviously simply typing ca a gets me Carl Anderson and Candy Ableton, but I'd rather the end user not need to do that.
