The invention relates to a method and a system for searching and querying documents (17, 18) relating to at least one predetermined search item within a data space (15, 16). According to said method, the data space (15, 16) is first searched for documents (17, 18) and information regarding the sources of the documents (17, 18) and their contents are stored in a database (4). Once the search item is input, those documents (17, 18) that contain or relate to the search item are captured using the information contained in the database (4) and at least a part of the documents (17, 18) captured are made available to a user. For updating the database (4), at least some sources of the data space (15, 16) are repeatedly searched for documents (17, 18), the search frequency depending on the updating frequency of the sources. It is also possible to establish for every document (17, 18) a quality rating that takes into consideration the origin of the document and/or an abstract of the document, which are also output. |
