This problem was reported here on dewiki.
- Search for Jan Nepomucen Umiński on dewiki.
- The article doesn't exist yet.
- Therefore the search page apparently shows results from the Polish Wikipedia, indicated by the headline "Suchergebnisse von der polnischen Wikipedia" (i.e. "Search results from Polish Wikipedia")
- However: The search results which are shown are not from Polish Wikipedia, they are actually articles on German Wikipedia.
- The Polish article Jan Nepomucen Umiński is strangely not displayed, although the article exists since 2004.
