I use Duckduckgo, but I realised these big(ish) search engines give me all the commercialised results. Duckduckgo has been going down the slope for years, but not at such a rate as Google or Bing has.
I want to have a search engine that gives me all the small blogs and personal sites.
Don't know if this fits your criteria, but I've been using Gruble a lot recently. You can personalise the look and language in the settings, plus it's open source.
