I was explaining to an adult yesterday that using -x will remove x from his google results. He was stoked! Then he concluded further that he could use +x too!
I hated to have to disappoint him.
I hated to have to disappoint him.
e.g. "x y z" ~ "x y z" + "x y" + "y z" + "x z" + "x" + "y" + "z"
where "+x y +z" ~ "x y z" + "x z"
Still, I would imagine this isn't exactly the behavior your friend would have expected.
