At the very bottom of LocalSettings.php, I've set $wgMaxGeoSearchRadius = 30000; however, the effective search radius is still the 10km default.
I've manually passed coordinates to the Special:Nearby page, and listings will show if 9.9km away, but disappear once I specify a coordinate slightly further away.
I've kept all other defaults and I only have two georeferenced locations, so the $wgMaxCoordinatesPerPage setting shouldn't impact anything.
Are there any known bugs, additional settings I should change, or a hard codded max that I can't exceed? Ideally I would like no max radius if this is possible, but I'll be happy with a larger max radius if I can get one.
