For the installation you do not need programmer or web server knowledge. The complete installation needs about 5 minutes and all you will need is a text editor and an FTP program. The configuration can be changed at any time through a browser control panel. The visual design of the search results are easily customised to match the rest of your site by use of templates. It's a simple process to modify the templates with an HTML editor to make unique layouts. Documents can be searched in HTML, PDF, DOC or TXT format. Outdated documents are detected automatically and deleted from the data base. Therefore only the most current information is displayed to your visitors.
