Method for structuring and searching information

A system for structuring digitally stored information and methods for searching the resulting structure are described. The structuring system comprises a database comprising a number of cells arranged in rows and columns for holding pieces of data representing the information. Only one piece of data may be stored in each cell and the pieces of data contained in cells in one row of the database constitutes a certain information. This information may be files on a computer hard disk, pages on the www etc. An index for each unique piece of data occurring in the database, where each index table providing information concerning all locations of that unique piece of data in the database, a main index listing once all the unique pieces of data in the database together with a corresponding index table identifier, the index table identifier providing a link to the corresponding index table for that particular piece of data, are also necessary elements in the structuring system, The structure of the database/index system in itself provides fast and simple access to the information contained therein. The information structuring system and the methods for structuring and searching digitally stored information may e.g. be used in a search engine for the Internet, in a mobile phone, WAP or as a search system for retrieving files and controlling the information stored in a LAN or computer hard disk.
