The good news is that with the number of search engines available you are likely to find one that feels comfortable and will wear well on you. If you just want the facts, the simple interface of Google may appeal to you. If you want your search engine to make suggestions and give you a lot of options, Excite or Altvista may be just the ticket. The goal is to find what you need to find in the best way you can. Keep in Mind What You Are Looking For.
Search engines have limitations.
They should be used for limited purposes. Ultimately, what I am looking for when I search for anything is either an official site or a well-tended, comprehensive site put together by someone who really knows the subject matter. Those types of sites are my real targets when I use a search engine because I know that once I reach those sites, someone has collected the best sites and reviewed the information available on the Internet. In other words, I'm closer to finding information that I can trust, always an issue on the Internet. You'll have your best luck with search engines if you use them to help you find these gateway and expert sites rather than simply using search engines to find specific answers.
