As an alternative for both, try searXNG.
https://searx.space/ for instances.
https://github.com/searxng/searxng for the code, you can run your own instance.
https://en.m.wikipedia.org/wiki/SearXNG for the wikipedia article.
Personally, I find it returns much better results than anything currently available elsewhere. It reminds me of a time when search actually worked. Also, no ads and no tracking.
BTW, different instances can supply poorer results than others, so shop around to find the best one for you.
I disagree they did a great job with The Expanse. The first three series are better IMHO, especially series three. The Amazon seasons just feel like a loose collection of bottle episodes in comparison.
