I think Olav's point wasn't "I plan to write an algorithm" but merely "what makes my street name show up when I do a search on www.openstreetmap.org". Olav - you *don't* need to put is_in on ways representing streets. The search works by looking for named items (not just streets) which are close to the place you ask for. But it *does* help if you put is_in on places. At present to search within a place needs a comma in the search, as in "John's Road, John's Village" If there are two John's Villages in the world, you can limit the one you mean with a third term, "John's Road, John's Village, County" in which case the third term is looked for in the is_in or the place. As I say, at present the comma is necessary and you can't give both country and county, and other limitations. However, I'm working on making this much more free format. That will work with no change needed to the data, but searches will more likely find the result if is_in on places is used.
