iPhone Text entry with completion and DONE button (not search)

Question

Using iPhone SDK 3.0, I wish to allow text entry with (optional) completion options that appear as typing is occurring, i.e. also allowing freeformat entry. As such I am using a UISearchBar (which has the text change events) and a UISearchDisplayController to present options.

The problems is I want the DONE button to say DONE and not SEARCH, however I cannot find a way to set that. Clearly I feel I am missing something, or Interface Builder of the SDK API would have some property to set.

I have seen other apps (in the store) that have achieved the result I want (free format entry, completion, DONE button) so maybe there is an alternative approach I am missing. Thanks in advance for any pointers.

+1 For wal's answer, but to be on the safe side, and properly react to possible changes in the view hierarchy in further releases consider using this code:

NSArray *subviews = [<searchBar> subviews] ;
for(id subview in subviews) {
    if([subview isKindOfClass:[UITextField class]]) {
        [(UITextField*)subview setReturnKeyType:UIReturnKeyDone];
    }
}
