My own belief is that everything is tracked anyway. For a few years I used things like Tor - but have finally just given up.
However there are search engines which give more useful (at least to me) results than Google
My favorite for the past few years is Carrot - which groups results by logical clusters (such as general sub-topic, web-address etc) as this allows faster weeding out of irrelevant results:

The first clustering engine I tried underwent a variety of name changes and is now called "clusty.com" and is, I believe, owned by RW nutters and so now stay away. The reason I think this is that several times when searching, the terms are rejected with a big "Not On MY Web you don't!!" This occurred when I was looking for sources for a talk on obstetrical complications and, most amusingly, when I was looking for drivers for a video-card which apparently had an unacceptable to Clusty name.
The most innovative, but disappointing, search engine (which is called a "computational knowledge engine"
which I continue to try every few months (and which has NEVER - in well over a hundred trys - returned a useful result) is:

In the past have used both DogPile and DuckDuckGo - mostly because of the names - but they do not offer clustering and return fewer results than G. Heck, have even tried Bing - again it has no advantage.
Try carrot - I think you will appreciate the presorting.
