Question about field Location (search)

I know you'll add field types to search forms in the future.
Do you think it will be possible to search the "Location" field of the profile?
Eventually, I would like to be able to search for members by city, region, country ...
Or is it better to create independent fields with lists like in dolphin?
I wonder about the best solution in my case.
I also think of the interest of being able to look within a radius of x km ... which would be possible with the first solution and impossible with the second.
What is your opinion?
