Hi,
We have made a few fresh installations of Nominatim lately according to the
documentation on http://wiki.openstreetmap.org/wiki/Nominatim/Installation
Our installations sometimes give different results than the official on
nominatim.openstreetmap.org. So far we have seen the following differences:
1). Hits in Norway and Australia get the country code aq (Antarctica)
Query:
http://nominatim.openstreetmap.org/search.php?format=json&q=spektrum,oslo&addressdetails=1
Result:

The main difference is:

"country":"Norway","country_code":"aq"
2). Differences in importance

3). Places not found using structured address search
Query:
http://nominatim.openstreetmap.org/search.php?format=json&city=tao%20yuan%20xian&country=taiwan
10 places found on nominatim.openstreetmap.org vs 0 on our server.
I attached debug output from our server
Any ideas what may be causing these issues?
Our setup is something like CentOS 6, postgresql 9.3, PHP 5.3, Python 2.6
We've used both Nominatim 2.1 and 2.2 for import with the same results
Best regards,
