PURPOSE:To utilize retrieval date as advice data, and to raise the information retrieval efficiency, by counting up a key word stored in retrieval information, and displaying its result together with the key word. CONSTITUTION:A data file 1 consisting of a large capacity memory stores plural information and key words. Retrieval data is inputted from an input part 2, is registered in a memory 3, and a data input signal is applied to a control part 4. The control part 4 gives an operation command to a retrieval system analytic part 5, and inputs retrieval data registered in the memory 3. The information retrieved from the file 1 and fetched to a retrieval part 6 is inputted to a prescribed information output device. The key word provided to the control part 4 is registered and stored in order in a key word memory 8. Also, data counted up by a key word reading-out circuit 9 are transferred to a display controlling circuit 10. |
