27. A method for searching and retrieving information about objects of an arbitrary application domain in the system for storage and retrieval of a plurality of information objects according to claim 1 , comprising the steps of: a) generating a search mask comprising information relevant to the information to be retrieved from said system, and said search mask being an information object (IO) with a tree structure similar to the tree structure of information objects stored in said system, b) generating based on said search mask an active query object (AQO) comprising search criteria, c) comparing the AQO with IOs embedded in a each of the plurality of active units of storage on the logical storage network of said system, wherein moving from AUS to AUS following existing logical connections between them is performed in the direction of decreasing metric distance between the information objects incorporated into AUS, and d) retrieving an IO meeting the search criteria specified in the AQO.
34. The method according to claim 27 , wherein search parameters include at least one of: a required degree of actuality of information returned by search, a frequency of data updating on the logical storage network, a degree of loading the nodes on the logical network by queries, capabilities of computer systems and throughput of channels connecting them, a number of metric distance calculation operations, a required relevance degree of returned information, and time allocated for each individual search procedure.
