Tasks in web search are often rather simple, e.g. navigating to an already known web page or looking up a fact. However, tasks in other domains are usually more complex and diverse. Thus, we discuss various search modes of tasks and how they might be supported by functions of a search system. We give examples of the required search functions of dierent search modes and describe the implications for the design of search systems.
