SearX is a search engine recommended by privacytools.io. I liked the idea of a fully open-sourced and user controlled search engine and I also installed a docker image with SearX in my local machine which works great. Eventhough I installed SearX I dont fully understand how it protects users privacy in a private instance. I know it is a meta-search engine which aggregates result from popular search engines.
I am using google,bing and yahoo as the default search engine in my local SearX. When we search for something in our local SearX it should send our IP address and keywords to these three search engines simultaneously and then SearX fetches the result and show us in our local SearX. Now these three have all our keyword search details and ip addresses comparing to if I sticked only to one search engine. How SearX private instances protects users privacy?
