Users submit their queries by filling out fields in a form. With Index Server, the administrator for a Web server can create customized forms to help users find documents at the local site. The administrator can modify the form so that the user can search by contents or by other document properties, such as author or subject. The administrator creates a query form with standard HTML, and the form becomes little more than a Web page itself. Any user who knows how to create Web pages with HTML can put together a simple query form in minutes.
