I use Startpage or Duck Duck Go to do my searches.
Also, I browse with Firefox, with the NoScript extension installed and running. By doing so, I can (1) see what is trying to run quietly in the background and (2) block anything I don't want running in the background. Shockingly, just about every website you visit has Google scripts running in the background; I block all Google scripts from running except for those associated with Google Maps. Occasionally I will temporarily allow Google scripts to run if I can't avoid it.
Even this site (thearmorylife.com/forum) is running "googletagmanager.com" scripts in the background, or trying to (I have them blocked).
(About the only heavily trafficked site I have found that doesn't run Google scripts is Microsoft.com (and all of their sites). And you will be hard pressed to find Microsoft scripts running on any site other than their own sites.)
But even with all of that, I'm sure that Google figures out a way to spy on me. I'm just making it a bit more inconvenient for them.
