[Geocoding] nominatim installation

[Alessandra Donnini]

Hello 
I'm trying to install nominatim on centos, I had some problems (also with selinux)  but now population seems ok, I see a lot of table in postggres, but most seems to be empty.
I tried to install Italy data.  
The last command to install special phrases goes wrong because I set database user name from www-data to apache before to execute the command and and the sql refers www-data user. 
My problem is that nominatim doesn't work: the site is available, but if I search something like Roma or Rome it answers "no search results found". 
How can I verify that data are loaded?  I need nominatim data to run other applications. The map in the local site doesn't show to me the box around Italy.
I have no error in access_log and error_log from httpd.
Is there a nominatim log?
thanks
Alessandra
