@paul1149, Google has one of the biggest data base, but apart privacy the bigger problem is the filter bubble effect in search engines which logged the activity of the user, its like asking someone which always agree with you, even if you are wrong, shows always results to your like as first result.
The alternative is to use Startpage or a Whoogle instance, which use the Google base, but without the trackings and loggings. Same for Bing, using DDG or Ecosia. Alternative searches with own bases, like Mojeek or Groot. Also Andisearch, which I use as main search, it has an own crawler with AI and gives accurat and objective answers, apart is one of the most private searches out there.
