Geocoding and getting better address location score

ThomasMcCracken

Afternoon everyone in ESRI Flex API land,

I'm having a little trouble getting a better match to come up in my geocoding.  I'm trying to add a for loop to the code like below:

for(i=0; addressCandidate.score>80, i=10; i++)
{
if (candidates.length > 0)
                    {
                        var addressCandidate:AddressCandidate = candidates[0];
                        var myGraphic:Graphic = new Graphic();

....

}

I've tried several variations of this loop with the candidates array and putting it within the if statement but no luck.
Basically I just want to add a loop to go through all the potential address matches until a score of 80 is reached on the match and then continue with the rest of the Geocoding function found in the API Samples for geocoding.

Anyone attempted to do this and have any luck?  Care to share some code with me??????? =D

Thanks,

Also, as I remember Location Service has alot of configurations on server side, so you can try sort, filter ... results on server.
