Exploratory Search
• What, if the user does not know, which query string to use?
• What, if the user is looking for complex answers ?
• What, if the user does not know the domain he/she is looking for?
• What, if the user wants to know all(!) about a specific topic?
• ...,Browsing‘ instead of ,Searching‘
• ...to find something by chance, i.e. Serendipity
• ...to get an overview
• ...enable content based navigation
