The engines on the bottom of the list have been supplied to show you something very important, We don't suggest using them, unless you absolutely have to buy something. They should be your last resort in most cases, The engines on top stay truer to the original spirit of the scientists that brought both the Internet and the Web to life. They wanted to spread light, and knowlege, not push products. Unfortunately corporations have corrupted this dream. Without a firm grasp of how to use these powerful tools, the treasures of the Web will remain forever beyond your grasp.
Novices are often mislead into using the weak proprietary search engines supplied by ISPs.
The problem with doing this is they're deliberately designed to be both dishonest and stupid. Use of the more powerful tools will let you escape their trap. They'll never be able to keep you down on their farm again, once you begin filling your hard drive with the many free goodies chatters will never find in the dungeons they inhabit. Road testing a few of the top tools against the commnercial ones at the bottom will make this point clear. Try running a search for something exotic, like red sill gloves, then try running one for something common like home page building.
