First of all, not all search engines are created equal. Often you will find something with one search engine that another failed to find. At the bottom of the page are some guides to using search engines. These guides will help you decide which search engine is best for your purpose.
Some people think that if they just connect to the internet they can find everything imaginable. The internet may have alot of useful information, but it does have it's limitations. It is generally the people that do not know how to use the internet that think it holds everything imaginable. If you can't find something on the internet you might want to consult your local library. Librarians can be very useful in showing you where the information can be found.
The last warning is to be wary of any information found on a web page. Anyone can put up a web page and it is often impossible to verify if that person is any expert or if they are just some goof-ball. Verify all information found on the internet.
