Most search engines use databases. Some search directories or web
addresses directly. Some use spiders to collect data. Search engines
are as varied as the kinds of jobs they do. First, decide what needs
to be searched and what searched for. Then research it. Don't just
plug a stock program into a slot and expect it is going to do what
you want. If you have ever explored college websites, you might
notice that most are large affairs that often have a lot of
disjointed and poorly organized pages. Most try to solve bad
organization with a stock search engine like ht://Dig or Ultraseek,
without realizing that for many prospective customers, it is a lame
solution. The ideal, on the other hand, could be a lot more expensive
and time-consuming to put together. In any case, take stock of your
customers and what they are looking for, and do the research to find
something that comes close.
