I’m testing using a browser per se, but instead I’m testing with jMeter. I’ve recorded the calls to pwiki.php using a proxy and I’m “replaying” it with jMeter, modifying some parameters before it.
When I pass an urlref with value “test - Пошук Google” piwik corretcly identifies it as a search engine an account it properly.
If change the value for “Monitore o presente, enxergue o futuro.” the visit is not account as a search engine. This lead me to the conclusion that the problem has to be with my configurations used to add Busk as a search engine, right?
Sorry, I added those lines to piwik/core/DataFiles/SearchEngines.php, simulated a visit with the Busk referer, and it worked for me. I’m not aware of any black magic involved.
