When you have to click it's not searching it's browsing (and in editors users dont want to click when searching for a tag). The use case is: given a search term return a ranked result set. That's more than just improving the display. And we need an API of that which can be used in editors like JOSM. >> That's why I suggested something I called "TagFinder".

We included a parser of related terms (as templates) in OSM wiki pages so that users can give hints.

I'm sorry to take a closer look at this: A search for... * castle gives 5th pos, but should list "historic=castle" on top [1] * Schloss lists archeological_site and castle at pos. 16/17 [2] * church return three weird lines [3] > As I said this is very very basic, but it is actually usable and could be > useful.

I hope you understand that this is not usable in our use case and that we are taking your offer to take it up with caution. -Stefan [1] http://taginfo.openstreetmap.org/search?q=castle#fulltext [2] http://taginfo.openstreetmap.org/search?q=Schloss#fulltext [3] http://taginfo.openstreetmap.org/search?q=church#fulltext _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
