For example, when a combination (group) of the IPC and the free word is repeatedly input, the group is determined. Type determination processing and search expression generation processing are performed within the cycle as one cycle, and type determination processing and search expression generation processing are also performed between groups using the one cycle as one search condition. Is used to generate a combination search expression, and information (patent gazette) corresponding to the search expression is stored in C
The D-ROM device 14 retrieves and reads the data from the CD-ROM, and displays the data on the screen of the display 11. That is, the computer main body 10 constitutes a search value periodicity determination section (periodicity recognition means) 61. Note that, for example, when a group in which several search items are followed by a characteristic search value (applicant, application date, etc.) is repeatedly input, the search is performed before the characteristic search value. When sorting for each item is required, search values may be sorted within one cycle by search condition sorting processing.

Next, the search processing procedure will be described together with the operation using the flowchart of FIG. By selecting the search and reading mode and performing steps P1 and P2, the input search item, relation, and search value are displayed on the display section of the display screen 11a.

At this time, since the search values of the similar search items are combined between the groups, they are connected and combined under the OR condition. In addition, the group of the applicant and the filing date of the group of IPC and free word shown in FIG.
It will be connected and combined under the D condition. Therefore,
For example, when a free word specific to a specific IPC is input, the intention of the order in which the search value of the user has been input can be reflected in the search formula. Even when the applicant and the period of the filing date are input, the intention can be reflected in the search formula.

Thereafter, by clicking the all search button 46, the patent publication corresponding to the generated search formula is stored in the CD-RO.
