It's the same on YouTube. One time I added a negative term and I ONLY got that term in the results. I don't understand how you can break such an important part of search.

I've used terms like "ItemA"+"ItemB"

And still get results which have the disclaimer "Missing: ItemB | Show results with: ItemB"

I ALREADY TOLD YOU TO

Yeah, so they changed it so it defaults to the "new" way where quotes and -UnwantedTerm don't function the way they used to, but when you fill out the search box, hit "Google Search", and it fails to perform the way you want it to, once you're on the results page, go to "Tools" click on "All Results" and change it to "Verbatim".
