I use https://searx.me/ https://searx.me/ specifically https://searx.bar https://searx.bar for controversial topics. Google seems to often times redact content and once during a academic research project in advanced military technologies me and my colleages even got "white-screened". Searches returned empty results, which resulted in many results previously. This on all my devices and friends devices also even though they were on a different network and location. A few days later the results came back, it appeared to us like a screening, before taking serious action. Our prof got nervous and handed us some information in case we get prosecuted or imprisoned for our research topics.
