Sogou started sending many hits with new referring URL syntaxes. Can you please add them so that Piwik recognizes them as Search Traffic from Sogou instead of Website Referral Traffic?
And these mobile referring urls, with search keywords included. ("mykeyword" here)
For the last one, I'm not sure what's the difference between keyword vs htprequery parameters... maybe one is what the user entered, and the other is the corrected/suggested version... but I'm just guessing here.
Either way keyword seems to be the main one, the other htprequery is only present in a smaller number of URLs.
