Abstract

PURPOSE:To eliminate the need of describing minutely the entry of a complicated expression and a conditional expression every time of retrieval by designating a retrieval conditional expression and a retrieval condition of a numerical attribute key item from in a list by an operator, so that a file of a numerical attribute can be retrieved. CONSTITUTION:A retrieval condition designating means 9 of a numerical attribute key item designates a desired retrieval condition in a retrieval condition list displayed on a display device 5 by an input instructing device. Also, a retrieval conditional expression fetching means 10 of the numerical attribute key item can fetch a retrieval conditional expression corresponding to the retrieval condition of the designated numerical attribute key item from a retrieval condition table 11 of the numerical attribute key item. In such a way, since the retrieval condition can be designated by a list, as for a numerical logic retrieval expression used frequently, it is unnecessary to describe again by an operator every time of its retrieval, the burden of the operator is reduced, and also, since the operator does not describe the numerical logic retrieval expression, a retrieval error caused by a description miss decreases.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to retrieval of document and image (hereinafter collectively referred to as calligraphy and drawing) data stored in a storage device, and in particular, a method for retrieving numerical logical operation expressions. Regarding.

(Conventional technique #i) Conventionally, when searching for calligraphy and drawings in an electronic filing device, the method of specifying search conditions, etc. is to register the keywords together with the calligraphy and drawings in an external storage medium, enter the keywords at the time of search, Alternatively, a desired calligraphy or painting was retrieved by specifying a corresponding keyword from a keyword list.

(8 Problems to be Solved by the Invention) However, when specifying the calligraphy and drawing search conditions as described above, if the attribute of the input key item is a character attribute, a list of keywords can be displayed. However, when the key item is a numeric attribute, keywords cannot be created. Therefore, search conditions cannot be specified by list display, and the operator must write and input the desired numerical logical search expression to be searched. There was a need.

Therefore, even if a search error occurs due to a writing error, or if the numerical logic search expression is frequently used, the
There was a problem in that it required rewriting, which placed a heavy burden on the operator.

An object of the present invention is to provide a method for searching numerical logic expressions that eliminates the above-mentioned problems.

(Means for Solving the Problems) The present invention achieves the above-mentioned object by providing a filing device for calligraphic data that is registered together with keywords, a search condition expression for a numerical attribute key item, and a search for a numerical attribute key item that holds the search condition. a condition table, a search condition list display means for displaying the contents of the search condition table as a search condition list, a search condition specifying means for specifying a desired search condition from the list display, and a search condition specifying means corresponding to the specified search condition. This is accomplished by searching for a search condition expression by providing a search condition expression extraction means for extracting the search condition expression from the search condition table of the numerical attribute key items.

(Function) With the above configuration, the present invention allows search conditions to be specified in a list, so there is no need for the operator to rewrite frequently used numerical and logical search formulas each time the search is performed, reducing the burden on the operator. And again.

Since the operator does not have to write the numerical logic search formula himself, search errors due to writing errors are reduced.

(Example) Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a block diagram showing a method for searching numerical logic expressions according to the present invention, in which 1 is a central processing unit, 2 is a main storage device, 3 is an external storage medium, 4 is an input device such as a keyboard, and 5 is a display device. , 6 is an input pointing device such as a mouse.

Further, in the central processing unit 1, 7 is a search condition expression input means, 8 is a search condition list display means for numerical attribute key items, and 9 is a search condition expression input means.
10 is a means for specifying a search condition for numerical attribute key items; 10 is a means for extracting a search condition expression for numerical attribute key items;
Reference numeral 1 denotes a search condition table of numerical attribute key items stored in the main storage device 2 .

The search condition expression input means 7 inputs and controls the search condition expression input from the input device @4. The search condition table 11 holds search condition expressions for numerical attribute key items and their search conditions.

Further, the numerical attribute key item search condition list display means 8 displays the contents of the numerical attribute key item search condition table 11 as a search condition list on the display device 5. Further, the numerical attribute key item search condition specifying means 9 specifies a desired search condition from the search condition list displayed on the display device @5 using the input instruction device. Further, the numeric attribute key item search condition expression extracting means 10 can extract the search condition expression corresponding to the specified numeric attribute key item search condition from the numeric attribute key item search condition table 11. Note that the external storage medium 3 is a storage medium such as an optical disk.

FIG. 2 is a flowchart of the operation of specifying search conditions, and the operation of FIG. 1 will be explained with reference to this flowchart.

First, step 1 (hereinafter abbreviated as SL, other steps are the same)
, a search key specification screen is displayed on the display device 5 under the control of the central processing unit 1, the operator specifies the desired search condition using the input instruction device 6, and the attribute of the specified key item is determined (S2 ), if it is a character attribute, S3. Proceeding to S4, a list of keywords is displayed in S3, and the operator specifies a keyword in S4. The operation up to now is the same as before. Further, when the attribute of the key item is a numerical attribute, S5. Proceed to S6.

In S5, under the control of the numerical attribute key item search condition expression retrieval means 10, the search conditions and search condition expressions are retrieved from the numerical attribute key item search condition table 11 on the main storage device 2, and the numerical attribute key item search is performed. Condition list display means 8
Under the control of , a list of search conditions for numerical attribute key items is displayed on the display device 5.

In S6, under the control of the numerical attribute key item search condition specifying means 9, the operator specifies the search condition using the input instruction device or directly inputs the search condition from the keyboard 4. This control is performed by a conventionally known search condition expression input means 7.

In S7, under the control of the central processing unit 1, it is determined whether there is a key item to be input next, and if there is a key item that has not been input, the same process as above is performed for the next item from Sl, When it is determined that all the items have been inputted, in the next step 88, under the control of the central processing unit 1, the file is stored in the external storage medium 3 such as an optical disk, and a file of the numerical logic search formula that matches the search conditions is output. Ru.

Figure 3 shows an example of a search condition list display for the above-mentioned numerical attribute key items.
and search conditions are listed.

As described above, in the present invention, search conditions can be specified by displaying a list, so there is no need to rewrite frequently used numerical and logical search formulas each time a search is performed.

Furthermore, if the desired numerical logic search formula is in the list, the operator only needs to specify it.

Therefore, there are advantages in that search errors due to writing errors and the like are reduced, and the burden on the operator is lightened.

(Effects of the Invention) As is clear from the above explanation, the present invention allows an operator to search for files with numerical attributes by specifying search condition expressions and search conditions for numerical attribute key items from a list. It's possible.

Since there is no need to enter complicated numerical formulas and conditional formulas every time a search is performed, search errors are reduced and the burden on the operator is also reduced.
