A program, method and system are disclosed which senses the presence of a non-text object in a mixed object document to be archived in an information retrieval system. In addition to text objects, a mixed object document can contain non-text objects such as image objects, graphics objects, formatted objects, font objects, voice objects, video objects and animation objects. The invention enables the creation of key words which characterize the non-text object, for incorporation in the inverted file index of the data base, thereby enabling the later retrieval of either the entire document or the independent retrieval of the non-text object through the use of such key words. <IMAGE> |
