I did a search today for “add Google captcha to a website -wordpress” because I didn’t want any answers to include wordpress. On Google search this works as expected. On the brave search engine it still show answers predominantly with the word wordpress in the search results?
Yes! You are on to something very important!
USUALLY the minus “search operator” will either filter(remove) results by “explicit exclusion” or reorganize and demote by “relative algorithmic relevance”
It seems like the developers ignored or forgot about stuff like Search Engines 101 - Fundamental Basic Functionality.
Sadly, I haven’t seen any indication that “basic search filtering” or similar functionality actually exist in Brave’s Search engine.
