Google censors search results and this has been the case for years. Startpage, while offering some semblance of privacy, relies heavily on Google for its results and therefore both Google and Startpage are garbage when searching for anything politically sensitive. Case in point: search google.com for the exact phrase, quotes included, "fewer than 1% of vaccine adverse events are reported" and Google tells us that "No results found for "fewer than 1% of vaccine adverse events are reported"." As expected, Startpage also returns no results. DuckDuckGo on the other hand, which relies heavily on Microsoft's Bing search engine, does return some results, but the best results are returned by the Brave search engine.
Google has a search index. In other words, Google actively crawls the web looking for new and updated content. Bing and Yahoo do the same. Most other search engines, like Startpage, DuckDuckGo, Searx, etc., are meta search engines, meaning they depend heavily or entirely upon the corporate goliaths such as Google and Bing. The Brave search engine is a hybrid in that it pulls results from both the large search engines as well as from its own crawlers. I discovered the Brave search engine a short time ago and added it to my browser. So far, it seems to be better than any other engine i've found.
