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.
Does something like this exist?
The more obscure a web page is, the more likely it is to be indexed only by the large search engines (i.e. Google). There are search queries that return 0 results on DDG, but quite a few (relatively) obscure websites on Google. This is simply because the more money a search engine operator has, the more websites it will index.
So what you want is kind of contradictory.
