How well does it work for non-English languages? I just tried it out for Swedish and had issues finding relevant results, especially searching for things like restaurants or hospitals.
In my experience from Denmark it is not great at the local results. However I don’t experience many problems with the Danish language. It is mostly stuff like if you search for some generic term that exists in both English and Danish. Then you might want the local one. This does not work very well.
But adding stuff like site:dk helps.
