A network (for example: the Internet) based information retrieval system is described. The system is associated with a plurality of users, each user being associated with none, one or more other users. The system includes memory means, which may be in the form of a distributed memory, which stores a table of associations between respective said users and a constellation of data divided into items of information. Each user has a portion of the data within the constellation associated with them. A specific user accesses the memory means and selects an alphanumeric data string to be searched. The system identifies from the table of associations those users, if any, associated with the specific user; and identifies within the constellation occurrences, if any, of the selected data string in data associated with the specific user or with any users associated with the specific user. Each information item within a said occurrence is identified is then displayed and/or printed. |
