1. Method for automatic searching and synchronous content display of a predefined set of documents in a displaying device in form of a list, characterized in that for each document encapsulated text extracts of various length are taken from the documents or synonyms of the said text extracts in form of natural language, the said text extracts or their synonyms are stored as data objects or—entities in a persistent data store e.g. as records in a database, detailing relations are created defining couples of the said objects wherein one object states more precise the meaning of the other, the said detailing relations are mapped by attributes of the objects containing references to longer, enclosing and therefore more precise text extracts (shorter, enclosed and therefore less precise text extracts respectively), thus creating chains of text extracts from the mapped detailing relations which start for example with words extracted from documents and end with headlines and assigning each of the text extracts of the said chains to a longitudinal class enabling queries of the data store by a computer displaying a text extract assigned to a longer class after selection of a text extract assigned to a shorter class and thus gradually displaying an increasing part of the document and representing its content more and more detailed.
