How can I structure this 'within x radius' search logic?

I just read a similar solution on this thread. It dealt with sorting, but maybe the logic can help your search.

What Would It Take To Sort By A Calculated Value In Bubble?

Parabola would work well, i agree, and I had tried them, but they suggested it wouldn’t be quick enough and isn’t geared toward such speed. I will investigate Airtable - something tells me i’ll run into a speed issue here as well - I just wish that we’d have input from the bubble team on what this will take to achieve. Sorting by a calculated value is such a sticking point based on the forum posts and feedback.
