import_logs.py can't restore data from the access log

hi
i tried to restore data from the server (nginx) access log ,
the restore was successful without errors , and i got on the vistor log icons
server:NGINX 1.0.10
PIWIK :2.2.2
see attached screen shot

These icons mean that Piwik detected some “Site Search” requests for this site. Maybe your wesite uses query parameter q= or s= etc.

so please disable site search for this site and try again the re-import
