When I use the minus sign to exclude certain terms in my search, it does not exclude them. The image shows a Brave search where I used -crossword to exclude all entries with the word crossword. You can see that it did NOT exclude them.
Thank you,
John
This is known problem, search engine operators do not work on brave search.
Sometimes they do, sometimes they do not, as far as I know.
The search team knows about it and will make sure to bring this requested feature in few months (probably by August).
