Finally, I found that you have to modify CFIDE/scripts/ajax/yui/autocomplete/autocomplete-min.js, which is invoked with the autosuggest attribute and change the following from:
YAHOO.widget.DataSource.prototype.queryMatchContains = false;
YAHOO.widget.DataSource.prototype.queryMatchContains = true;
What a drag for anyone that has to get this changed on a production server...
The answer was found here.
EDIT: A better solution is to copy CFIDE/scripts/ajax/yui/autocomplete/autocomplete-min.js to a folder in your web, and then import that into your header, which preempts the version in CFIDE/scripts/ajax/yui/autocomplete. This is the only solution, if your sys admin doesn't want to make the change globally, (and who would blame them?):
