Yeah, at the moment, I just check if they received no results and offer to "widen" the search to all available relays, if they aren't already relay-maxxing. I was going to add a bit more logic, including fuzzy logic, to the initial search, to improve the returns.

But we can have a "deepen" button, as well. That fits the concept I had, to always go least-to-most, to be stingy with sharing the users' data and save computation and bandwidth.
