dataset sorting with wildcard

Does anyone know if it's possible to sort a dataset using a wildcard or some kind of "begins with" functionality?

My code so far:

part.text=partno;
prices_ds.filtered = true;
prices_ds.filterFunc = function(item:Object) {
return(item.Part == partno);
}

I am sorry, sometimes I am an idiot but I do not see where this code has anything to due with a wildcard or "*" which actually there is no wildcard in flash as far as I know.

Again, I am sometimes an idiot but..........

No, you're not an iditiot. This code doesn't have any wildcards in it. I was merely trying to show my method for filtering, hoping someone would have some insight about how to add wildcards.

In any case, it's a moot point now. After waiting almost 6 hours on hold for MM tech support, I'm told "it can't be done." Filtering has be done with exact matches.

MM? Macromedia? They have a tech support?

Not to slam Macromedia, because I know they've got a tremendous volume of calls, but it shouldn't take 6 hours to reach someone and then two days for a response copied from the online help.
