[OSM-dev] Nominatim results when limit=1

[Jason Lee]

Hello,
I have a service setup using the OSM Nominatim service and I have a query
on number of results returned with the "limit=" parameter. I have it set as
1 to only get the top result BUT when I search for "San Francisco" or
"Boston" (where countrycodes=us) I surprisingly got no results? I change
this to limit=2 and limit=3 and see that I get 1 and 2 results respectively
- which seems offset to me...

http://nominatim.openstreetmap.org/search?q=San+Francisco&format=json&limit=2&json_callback=geocodeResult&countrycodes=us
http://nominatim.openstreetmap.org/search?q=San+Francisco&format=json&limit=3&json_callback=geocodeResult&countrycodes=us

...on the other hand, searching for "Chicago" for limit=1 then 2 then 3, I
get the expected number of results...

http://nominatim.openstreetmap.org/search?q=Chicago&format=json&limit=2&json_callback=geocodeResult&countrycodes=us
http://nominatim.openstreetmap.org/search?q=Chicago&format=json&limit=3&json_callback=geocodeResult&countrycodes=us<http://nominatim.openstreetmap.org/search?q=Chicago&format=json&limit=2&json_callback=geocodeResult&countrycodes=us>

Is there a bug here or something I am not understanding?

Any advice much appreciated.

Jason
