In the past, I believe we could put a minus in front of a search to exclude results with that word. For example, if I wanted to search for pages with 'book' and 'face' but rule out facebook, I could use: face book -facebook. But that no longer works (most of the results include 'facebook' -- the opposite of what they should be). I also tried using the word NOT, but that just seems to add results that have the word "not" in them.
Or if I wanted to search for information on a topic and exclude YouTube results, adding a -youtube would do the trick. Or I have travel question and I don't want the spam results site of eclipseaviation.com appearing in the results (crowding out all the valid results), I should be able to just include -eclipseaviation. Or if I'm searching for magic beans and beanstalks, but don't want to see anything about jelly beans, I could just add: -jelly to my magic beans beanstalk search. None of these work any longer. This is a vital staple of standard searches.
Is Bing broken or has the exclude or logical NOT operation been changed or removed?
How can I perform a search and ensure only results that do NOT include a specific word or term?
Is there a current correct list of search operations like this? Seems this should be readily accessible from every Bing search. Isn't in Microsoft's/Bing's interests for people to know how to get the most out of their search engine? I can't find any instructions at all and the intuitive options (like just putting a minus in front of a word) don't work.
