How Google uses blacklists, algorithm tweaks and contractors for search results
If you actually read the article most of the statements of fact are about the omnibox autocomplete system, and then they use innuendo to imply some things about search engine ranking.  But these are two completely separate systems, and it makes sense that a system that is literally telling you what to type  is more sensitive than the search result ranking.  It is not a flaw of Google that it won't suggest "is hillary clinton still controlled by the jews" when you type "is hillary clinton". If it was just a big trie of what everyone typed, it would be completely dominated by 4chan troll bots.
