I was addind some new search engine website into Piwik and I see that Google added a new argument: as_q = KEYWORD
So I changed:
'www.google.fr' => array('Google', 'q'),
'www.google.fr' => array('Google', array('q', 'as_q')),
and it's working well...
Thanks, Jonas. This duplicates #1370, where you'll see there are other advanced
search parameters that need to be handled. This is fixed in svn and will be rolled out in the next release.
