PROBLEM TO BE SOLVED: To solve such a problem that the existence/absence of a desired image can not be judged with respect to retrieval results because only keyword retriev al in text data is performed in keyword retrieval in the conventional retrieval for texts with images. SOLUTION: A text part is separated from an image part, image file retrieval is performed in parallel with the keyword retrieval in the text, and the priority of data that hit both the text part and the image part is made high and is defined as retrieval results.
