Kagi has an option to search the Fediverse. This makes it a lot easier than specifying a site in the search query, which would also limit the results to a specific instance.
Why YSK: This lets you easily replace searches like “some topic reddit” with Lemmy!
Just yesterday I cancel d my Kagi subscription because it is based in the US. I liked it though, for the few years I’ve used it. Also a lot of good progress going on.
I switched to Qwant as it is European.
Qwant is probably the best free search engine at the moment tbh
