The same way that an index in a book maps an important word to a page inside the book, content indexing on a computer takes a word within a document and maps it back to that document. Where other Web Servers are limited to searching only HTML pages, Microsoft Index Server uses open standard content filters to index any file type, including Microsoft Word and Microsoft Excel documents. There is no need to change the way your business works just to share documents over an intranet. Microsoft Index Server is designed so that the indexing process occurs behind the scenes, requiring no user input and minimizing demands on system resources. Searches are made by simply filling in fields in a query form, which allows users to focus on what they are looking for according to a variety of parameters, including directory, subject, author, date, and file type. Because the query forms are created using open industry standards such as HTML, they can be easily customized to meet the needs of any site and can be used from any Web browser.
