Is it possible to make searches on Bing, Google or another search machine, that will only show results that is, for example, PG-rated?
For example, if I wanted to send a school student to search on the Bikini islands, a place where there has been done A-bomb tests, I'm sure it would be easy to get a lot of unwanted material in the form of swim suit pictures, magazines, etc. Would it be possible to get the search engine remove those results instead of using parental desktop tools, to block those sites?
