This is cool, and I’d love to see something like this in Mojeek.
The new Rerank feature introduces a panel on the search results page [that] lists domains, each with the option to thumbs up (raise) or thumbs down (discard) the domains from the results. From that point forward, raised domains will be boosted higher up in the rankings a user sees, while discarded domains will no longer be included among the results.
Rerank changes are stored locally in your browser’s cookie storage (which can be manually cleared at any time) and passed to search via a cookie. Similar to a user’s IP address and any other personally identifiable information, Brave Search does not use this Rerank cookie to track user queries.
It’s all cookie-based and doesn’t require an account. Mojeek Focus is similar but it has a limit of 25 domains. There are hundreds of domains I’d never like to see again.
