How do I stop google from searching a particular keyword in the future by someone else?

How can I stop a particular person's particular keyword search in google in the future? Is there a way to stop google from searching those particular keywords?

I dont mean how to clear the history.
I meant - how can I stop another person from searching a particular keyword (let it be 'xyz' for now) in google. That person should not be able to search 'xyz' in google in the future.i.e. the google searchtool should not be able to search 'xyz' again.

in google " -xxxx" excludes the word. but doin it with someone else is a hacking progress. But if you want to do that with your children there are some filtering softwares for that.

clear your history!

Other than making the search engines with more elaborate identity options for ownership there appears not to be at my present understanding of shared knowledge.

as i understand your question:

put cursor in search space & down arrow key than press delete.
the word u last searched will be delete.
I hope this will help u.
what did u search ? ha ha ha just kiding.
