Okay, I had a bunch of examples prepared of hits for known items in GBS. But a bunch of them have stopped getting hits from GBS! Things that used to be reported as ‘snippet’ view by the api are now reported as ‘noview’. Things that used to get matches as ‘noview’ now don’t get matches at all.
Bug? Consequence of the GBS settlement? Consequence of routine record reloading and manipulation by google, that causes the google corpus to change sometimes?
