Just one question though (well two acutally): why does it find 
Hovedvegen as nearest street and not Reingveien 
https://nominatim.openstreetmap.org/ui/details.html?osmtype=W&osmid=282670088 
?
And would it be an idea to make some kind of fuzzy matching when 
searching for names? Like "it is better to take a street which has just 
one different letter then one where all differ"?
