Well, this is partly the problem the Name Finder sets out to solve. You will notice that if you search for "High Street, Ely" (the one in Evesham, if there is one, isn't mapped, so I've changed the example) you don't get several results which are the component ways of that particular High Street (assuming there is more than one - I've not looked), but you do get other nearby High Streets. It would be easier to do this if the components were related, but it isn't an insoluble problem if they aren't. You don't get duplicates with the name finder for this kind of street. However, you *do* get *useful* duplicates for the M11. Not every single little piece, but at useful intervals along it. So if you say "M11 near Bishops Stortford" you get one bit, the nearest to the town (and then a few more successively further away), and "M11 near Saffron Walden" gets you a different bit. Because it is such a long road, as you say pointing at one point only on it is not helpful. So I don't. But pointing at every artificially divided up part of a road isn't helpful either. So I don't. David (PS I notice something's gone wrong with the sorting in the name finder - I'll look into that). _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
