In the top right search bar (for Google), it used to give me good search results, ie: Typing "ubu" would pop up "Ubuntu", "Ubuntu Linux", etc.
Now, "ubu" gives me "trippy", "triple mmm", and even "ubuntu lin" gives me "trishakrishnan", and some other weird hints.
When I press search, it searches fine. It's just the search suggestions that are WAY off.
What did I do, what is the cause, and how can I fix it?
