One article also says that encrypted search for logged-in users shows up as "not provided", but still is known to come from Google. I don't know enough to fully follow all of it, but the trend seems to be that less and less information is being provided, unfortunately.
Two tiers of obfuscation:
#1 referer says https:/ /www.google.something-here ... and that's all. Any analytics program worth its salt will recognize these as search-engine hits even if the other information is missing. (That is: It may not have recognized them the first time they appeared, but the form has existed for a long time now.)
#2 referer says http:/ /www.google.something, and query string says cd=some-number, but search terms aren't given. Can't remember if anyone ever figured out what these represent. "My page came in at #3 for ... well, something."
