Search engines are the services that you use to find websites on the internet. Google is the most popular search engine, by far, but is far from being the most private. Google is renowned for their ad network, which they unsurprisingly power with the data they harvest from their users. On top of the data harvesting, Google is actually becoming unsafe to use. When performing a search on Google, sponsored advertisements show up at the top of the results, hackers have started abusing this to make money. However, there is a solution, the same solution, in fact, to the issue of finding a good browser. Don't use a search engine that spies on you.
The answer is SearxNG. SearxNG is an open source search engine, that you can run on your own machine, or use a public instance. SearxNG is by far the most private search engine, if you self host it. If you don't self host it, you face the same problems you face with other non self hosted services, that is, you can't verify the claims about privacy. Using a public SearxNG instance is still far better than using Google, or Bing, or any other big search engine, but self hosting is thousands of times better. One of the really great things about SearxNG is how customizable it is. SearxNG doesn't work like most other search engines do, rather than crawling the web itself, it aggregates the results from other search engines. It does a little more than just proxy the requests to a larger search engine, though, it actually removes all the private information going to the larger search engine, and coming from the larger search engine, as well as some advertisement removement stuff.
It can also be set up to run through a proxy so that your ip address won't be revealed to the search engines being aggregated, you could even run it through Tor! One of my personal favorite features of SearxNG is the image proxy. When looking at the images section of the search results, all of the image thumbnails can be set up to be proxies through SearxNG so that way the service hosting the image won't be able to fingerprint your browser if you're just looking at it through the image proxy. Another really handy feature is the ability to select which search engines and databases will be used. This can be especially helpful for fine tuning results for a specific purpose, for example, if you do a lot of scholarly research, you could configure your SearxNG instance to only pull data from scholarly sources. You can even setup custom search engines, so that you can search websites that you would normally have to go to directly to search on, right from your normal search line!
It is also really easy to install, and has great documentation. There really are so many great features to discuss when it comes to SearxNG, I've covered a few, but I'll leave you to figure out the rest for yourself. I would absolutely recommend this search engine to absolutely anyone, after using it, you won't even want to go back to using Google, or Bing, or whatever other spyware garbage.
