I use the closest one to me from searx.space. I suppose hosting an instance yourself will give you the best response times, but it always still takes a moment while it searches through multiple search engines. If you only care about the results of one engine (e.g. google) then you could disable the others. Might speed it up a bit.
ok, so seems like I will have to use a double bang then. It does not seem match ddg bangs 1:1 though. And some don’t seem to be working correctly on my instance (E.g. !!mc for metacritic redirects to the wrong page)
