geocoding - OSM Nominatim search strange behaviour -

i have ran troubles using open street map nominatim search api. trying search , geocode addresses, queries, results quite strange.

for example, when use query:

http://nominatim.openstreetmap.org/search?format=json&countrycodes=cz&limit=10&accept-language=cz&addressdetails=1&q=jihlava 

i expected results - city jihlava.

but when use queries (only part of name):

http://nominatim.openstreetmap.org/search?format=json&countrycodes=cz&limit=10&accept-language=cz&addressdetails=1&q=jihl 

or

http://nominatim.openstreetmap.org/search?format=json&countrycodes=cz&limit=10&accept-language=cz&addressdetails=1&q=jihla 

or

http://nominatim.openstreetmap.org/search?format=json&countrycodes=cz&limit=10&accept-language=cz&addressdetails=1&q=jihlav 

i empty result list.

is there wrong query?

thanks.

that's expected behavior, now. nominatim has no auto-correction feature yet. partly matching queries aren't handled correctly.

if need auto-correction please see if 1 of other search engines osm fits needs.
