e. Search and query mechanism

In addition to navigational access to information, hypermedia systems should provide efficient search and query mechanisms. This would partly solve the “lost in space” (disorientation) problem experienced by users during navigation. There can be two kinds of queries – a structure query to retrieve a part of the network and a content query to retrieve a specific node. The former requires the development of a query language geared towards dealing with hypertext network structures.
