Abstract

This invention provides an information processing method and apparatus, which can automatically set a word, which has already been electronically stored, as a search keyword, and can perform a search operation. For this purpose, in an information search apparatus for searching a data file for desired data, and reading out the desired data, input text data is stored in a data storage area, and when extraction of a search keyword is instructed, a search keyword extraction program automatically extracts a keyword used for search from the text data stored in the data storage area in response to the instruction. A multimedia data file stored in a nonvolatile storage medium is searched based on the extracted keyword.
