A single search query corresponding to the search topic is received. The single search query is preferably in a natural language format. An index database is searched in accordance with the single search query to simultaneously identify document records and multi-media records related to the single search query. The index database has a plurality of search terms corresponding to terms represented by the text information fields and the associated text fields. The index database also includes a table for associating each of the document and multi-media records with one or more of the search terms. A search result list having entries representative of both textual documents and multi-media files related to the single search query is generated in accordance with the document records and the multi-media records identified by the index database search. Text corresponding to the search topic is retrieved by selecting entries from the search result list representing document records to be retrieved, and then retrieving text represented by the text information fields associated with the selected document records. Digital video or audio information corresponding to the search topic is retrieved by selecting entries from the search result list representing selected multi-media records to be retrieved, and then retrieving digital video or audio information represented by multi-media information fields associated with the selected multi-media records.
