GOOGLE? Are you reading this? Sounds like they’ve been doing a lot of tweaking trying to ensure that knowledge on that web page isn’t released. Google REALLY bowed in China, lapping at the feet of censor editors, I thought they were the KINGS of FREE SPEECH.
Also, keep checking the ‘Advanced Search’ options when using the search feature. Safesearch keeps defaulting on and Google filters out content from the returns with it. Google doesn’t allow the user to edit out search words, they seem to have their own picking and choosing of words.
