DuckDuckGo is about as good as it gets. If you are concerned about your privacy use a VPN (Virtual Private Network). They are dirt cheap these days... I have used NordVPN for the past several years. They typically have specials where the monthly expense is under $3 a month.
I’ve been having a problem using a VPN. I work with a window open to Xfinity. I cannot stream with the VPN operating. Haven’t figured a way around that.
