Basically, 20 results accounts for two full pages for search results from other engines. Both result quality and (typically) engagement beyond that drop significantly. Note that we are not perfect and we recognize that this particular approach does not necessarily work for all users.
This is something that we’ll be looking at carefully and considering for future releases to ensure that Brave Search works more efficiently for more queries and users.
Please remember that Search is still in Beta and is constantly being monitored and adjusted to give a smoother, more accurate search experience.
