Google definitely has a big lead with search engines now but there are some measures you can take if you want to stay anonymous.
You can prevent cookies from them but there is also a bit of _javascript code you can put into your address bar while on a google page to change your
cookie identifier to all zeros.
Oh and I'd recomend Scroogle as an alternative it still searches google but wont be
identified to you.
I don't care enough about my searches to do this myself though I admit and will continue to use google as long as the engine returns relevant results
although I do feel the search quality has taken a step back recently they are trying to localise the searches to much.
