Information retrieval of concise and consistent text passages is called passage retrieval. Passages can be used in an information retrieval system to improve its user interface and performance. In this thesis passage retrieval is compared to other forms of information retrieval. Implementation of passage retrieval as a feature of an information retrieval system is discussed. Various existing passage retrieval methods, their implementation and their efficiency are compared. I evaluated two different implementations of passage retrieval: direct passage retrieval and combined passage retrieval. In comparison combined passage retrieval turned out to be more efficient.
