I suspect that this is the direct result of AI generated content just overwhelming any real content.
I tried ddg, google, bing, quant, and none of them really help me find information I want these days.
Perplexity seems to work but I don’t like the idea of AI giving me “facts” since they are mostly based on other AI posts
ETA: someone suggested SearXNG and after using it a bit it seems to be much better compared to ddg and the rest.
Kagi is great. It’s a paid service but you can try 100 searches for free.
You can use the Orion browser on iOS and set Kagi as the search engine.
