@Jerome is referring to the search engine used by Kurviger, displayed at the bottom of the search list:
You can go directly to the website openrouteservice.org and perform the same search and some of the results will be omitted. I have also noticed this. It is a bit irritating because the closest and thus for me most relevant results are omitted. Why? No idea.
To illustrate it on a more simple example. I am looking for “Lidl” (both websites have access to my location and the map is centered on it:
This is what I got from maps.openrouteservice.org (all results within 600km radius)
And this is what I get from kurviger.de using the OpenRouteService search engine (first result on Philippines!?):
Obviously, the search engine knows the locations that would be of more interest to me, but Kurviger omits them completely. I hope it is only a matter of a wrong argument passed to the search engine API and this can be fixed quickly.
