The Web searches so many documents that search engines have to ask for lots of information up front. The problem with that is, you don't always know exactly what you're looking for. You may just have a vague idea that you need some information that was somewhere in an email or document. With SIS, you can type in your best guess, such as 'set up a blog,' and then you can refine the search, filtering by the type of document, from an Excel spreadsheet to a Power Point file to a music file and more. You can further refine by date, rank, author or other properties that you remember about the document.
