Recently we upped the radius for searches on Wikivoyage to 20km. This still isn't probably enough for certain towns.

Is there anyway we can increase the maximum radius here (what is the highest we can safely go to?) and incrementally increase it when no search results are found. e.g. search within 20km, then within 30km, then within 40km all the way to 50km?

There is some cool discussion going on here: and it will be great to help out the Wikivoyage community.
