Try using Kagi search. It’s a subscription based search engine, but it’s much more customizable and doesn’t serve ads or push shopping pages at you as solutions. You can save a filter on there to exclude results from

Reddit and Quora if you don’t want to see them in your searches, but you can also specifically mention websites to whitelist if you find they give you good results for certain types of searches.

I still use Google occasionally because the one thing Google is great at is recommending products to purchase.
