Been using brave browsers new search engine for the past month and its been way better than google, but just read one of their whitepapers for the "goggles" feature they are working on which you will be able to use to create filter lists and search through curated lists.

Heres something I grabbed from the paper

We envision a scenario where a community of people create and
curate Goggles like,
• "Tech Blogs". Imagine searching through a collection of
personal and company blogs curated by the community.
• "Product Reviews without commercial intent". Get rid
of all sites with price comparisons, affiliate links, etc. Basically, to browse over product descriptions and reviews.
• "Independent Media for any country". Would demote
major newspaper and promote minor outlets.
• "Exclude top 1000 domains". Would remove results from
most popular domains on the Web to surface less prominent
ones.
• "Recipe search that my mom likes". Only searches recipes
on tasteofhome.com, nowhere else being considered, would
become a site search.
• "Nature lovers in the Pyrenees". An extremely curated
list of high-quality sites for hiking/trekking in the area. Excluding the more generic sites not specialized in that area.
• "Wikipedia / Reddit / <Any site> search". Site search is
just an instance of what Goggles can be. The other way round
also works; results that exclude results from a given site (e.g.
********).

Soon we can build curated lists of the best misc threads, lookmaxxing techniques, instagram thots and conspiracy theories.
