To fix that please delete all the wikipedia=McDonalds tags from<br>
the McDonalds restaurants that show up inappropriately. Nominatim uses<br>
the wikipedia links to determine how well known a place might be and<br>
ranks places with a wikipedia tag higher. That naturally only works<br>
when the wikipedia tags actually link to a wikipedia page that<br>
describes the object. It leads to funny results when the link goes<br>
to category pages or, like in this case, to the company description.<br>
<br>
Alternatively: I've proposed a GSoC to overhaul the Wikipedia<br>
importances that Nominatim uses. Getting rid of this particular<br>
problem from the Nominatim side would be part of this job.<br>
<br>
For more information, see:<br>

<br>
There are also two other topics proposed and if you have another particular<br>
itch you want to sratch, there are surely ways they can be transformed into<br>
a GSoC topic. Just send me a email or open an issue in github. It would be wonderful, if<br>
we find some students interested in geocoding this year.<br>
<br>
Kind regards<br>
