What if you just research things related to the world? Is that such a problem for a search engine to bite you int he butt later? What search engine do you use? They don't need you logged in with an identity wither, they can track with browser and IP probabilities to identify you. It's all tracked and will it ever change? How can it be changed other than us not using services that track our data? Isn't it essentially omnipresent? I have GPS disabled on my phone though hehe.
