A non-textual data searching system according to the invention is capable of searching non-textual data at semantic levels above the fundamental symbolic level. The general approach begins by indexing the non-textual data corpus in such a way as to facilitate searching. The indexing process results in a number of "keytroids" that represent clusters of fuzzy attribute vectors, where each fuzzy attribute vector represents a data event associated with one or more non-textual data points. The actual searching process is analogous to a conventional text-based search engine: a query vector, which identifies a number of fuzzy attributes of the desired data, is processed to retrieve and rank a number of keytroids. The keytroids can be inverse-mapped to obtain data events and/or non-textual data points that satisfy the query.
