Using Map Compare, I sometimes use its attribute "Center Location" with a radius. I now found out, that when the named Center (typing will find it) is not a city or the like, but a POI, I get no caches then. Using the city nearby presents a lot of caches.
Example (by typing the location into the adequate field):
Call "Map Compare" from menu, fill "Profile Name" adequately, Cache location's Country (i.e Germany)
Select "Show: None found, One found"
Add Filter "Center/radius (km)", fill "Radius" e.g. 50
Fill "Center" with "Boglerhaus...." (Rest will be provided) --> press "Filter"; Result "0 Cache...." (in two lines)
Fill "Center" again now with "Friedrich-Bogler-Straße..." (Rest will be provided) [this is the street where Boglerhaus is located :-] )
--> press "Filter"; Result "many caches"
Any idea?
