There are millions of InterNet sites, scattered all oever the world. Looking for something specific is like the proverbial needle in a very large haystack. To make seaching possible, a growing number of on-line search services have been started. Most of these services are easy to use, but NONE of them are complete . Every search service works a bit differently, so it is a good idea to try them all at least once and look at the results.
