In this paper, we present DynaQ, our prototypical inquiry system to explore the personal information space that supports the user with the help of the searching paradigm Orienteering, achieved by using dynamic queries. Orienteering is typically characterized by relatively small steps following one after another. In contrast to searching through keywords, Orienteering offers several advantages: reduction of cognitive load, sensitivity of the environment, and a better understanding of the results. Dynamic Queries enables the user to specify search queries in a dynamic way to get immediate feedback on changes inside data sets that fulfill the query criteria.
