To fix that please delete all the wikipedia=McDonalds tags from
the McDonalds restaurants that show up inappropriately. Nominatim uses
the wikipedia links to determine how well known a place might be and
ranks places with a wikipedia tag higher.
I would expect that a bounding box has precedence over other tags. Why
would a wikipedia tag have precedence over the bounding box and a name
But then I still don't understand.
In the bugreport I have the example of the shop "kruidvat" (it is a
chain of stores in the Netherlands).
The bounding box is 6.16575,51.36926,6.17049,51.36759 which centers on
the Kruidvat store in Venlo . Nominatim returns the kruidvat in
Both nodes have a website tag with the same value. Both nodes have the
same tags, expect that one has a source tag.
Then still, why is the boundingbox not looked at _at all_? It's not like
it's the second or third result, it is the 12th result where all other
results have similar tags and the results are the same whatever bounding
box you use.
I can accept that the website tag raises the ranking, but that doesn't
apply in this case since all nodes have the same website tag. It still
looks like the bounding box is not used at all.
I have another example:  centers on a restaurant called "Sint Maria"
Entering this in Nominatim  gives tram stops in Brussels, churches
and graveyards in Germany. None of which have a website tag.
