We can't imagine a web site without at least a rudimentary search functionality. What a frustration when we shop for a particular product or looking for an answer on a community web site and can't find exactly what we are looking for. The search is the paramount for any online business. If a customer can't find a product she's looking for, she would go somewhere else and you lose a sale.
Unfortunately, most of the databases don't provide full-text search capabilities or provide a minimal support which is not enough in most of the cases.
