Not sure if this is possible, but is there a way to list all users who specify a given location as their \"current city\" using the Graph API or some other means?
If you see Facebook notification when you try to search but found nothing, it says:
Looking for people or posts? Try entering a name, location, or different words.
You can add location to the query, like: my_name my_location --> "Aminah Nuraini" Indonesia
It will only work if the user allows people to see their location, though.
