The invention concerns a system comprising means for encoding data concerning said objects by (a) setting up a table (T) with hierarchical structure of the set of attributes (Cna) and contents (Cnu) associated with said objects; and (b) setting up for each stored object a file wherein each attribute of said object and its contents is identified by the specific code assigned to said attribute-contents pair in said table. Said system comprises calculating and interfacing means for, in response to a search request from an applicant, (c) constructing a first table containing the set of stored files concerning a request; (d) constructing a second table containing the set of contents present in any one of said files of the first table; (e) presenting the successive selections of attributes and contents to said applicant, in the hierarchical order defined in said second table; (f) updating the first table by selecting in said first table the files comprising said selected attribute-contents pair; (g) repeating said operations e) and f) until at least one predetermined condition is fulfilled; and (h) presenting the result of said search to said applicant when said condition is fulfilled.
