Abstract
An information retrieval apparatus retrieves information from a database. When a retrieval request is received from a user, a first retrieval section retrieves information from the database using a retrieval expression in the retrieval request. A retrieval result memory section stores the information retrieved by the first retrieval section. If a new retrieval request is not received and detailed information corresponding to the retrieval expression is not stored in the retrieval result memory section, a second retrieval section retrieves more appropriate information from the database using a modified retrieval expression and/or more sophisticated retrieval algorithm.
