I know it’s been getting worse over time, but I could still find what I needed after some digging.
Recently it’s been like 10 minutes of adjusting search terms, still getting completely useless or irrelevant results, and me just giving up afterwards. Other search engines seem just as bad.
FWIW, the default “programming” lens works quite well in Kagi, you can also create your own lens if you have a set of websites from which you routinely search info, and there are tons of bangs already (which can also be mapped to lenses BTW). In addition, you can downrank AI/SEO stuff when you find it (it is downranked by default in kagi), so that over time your results are quite clean.
