After DuckDuckGo, I used Gigablast for quite a while, but it looks like it was recently shutdown without any announcement or notice. After using several search engines, including Startpage, SearX(NG) and LibreX, I started using Mojeek for the last few months, but very recently decided to go back to Startpage for now. It is one of the few ties I have with Google, even though the relationship is indirect.
