2. Description of the Related Art Conventionally, an electronic notebook, a word processor, a personal computer or the like has a database function and can store documents and data. In this way, when searching for and displaying saved documents and data, you must enter the data search command, put the device in data search mode, and then enter a search character string such as a keyword. I had to do it.

After the target data is searched and displayed by such an operation, if the same data is searched and displayed again by using the same search character string, after the search command is input again, Since the same search character string as that used must be input again, there is a drawback that the re-search operation in such a case is complicated. In addition, when the keyword used last time is forgotten, it is impossible to search under the same condition, and it is not possible to obtain the same search result. However, the search character string is a general term for keywords and search conditions.

[0004]

In the conventional data search method, data is searched once using a certain keyword or search condition, the result is obtained, and then the data is searched again using the same keyword or search condition. If the user wants to do so, the operation of inputting the same keyword or search condition as the previous time must be performed, and there is a drawback that the re-search operation in such a case is complicated. In addition, if the user forgets the keyword or the search condition used last time, the search cannot be performed under the same condition, and the same search result cannot be obtained.

Therefore, the present invention eliminates the above-mentioned drawbacks, simplifies the operation for re-searching data by using the same search character string, and can always perform the same search character string again. An object is to provide a data search method and a data search device.

[0006]

The present invention provides a data retrieval method for retrieving data specified by an input retrieval character string from data stored in a storage device, which is displayed on a display device. An arbitrary search character string is registered in advance in an arbitrary tag among a plurality of frame-shaped tags, and an arbitrary search character string registered in the tag displayed on the display device at the time of data search is displayed. When selected, the method has a method of searching the data specified by the selected search character string from the data stored in the storage device.

The present invention relates to a data retrieval device for retrieving data stored in a storage device and displaying it on the screen of a display device, comprising first display means for displaying a plurality of frame-shaped tags on the display device. A registration means for registering an arbitrary search character string in an arbitrary tag among a plurality of tags displayed on the display device by the first display means, and a registration means for registering the search character string in the tag at the time of data search. Second display means for displaying the searched character string together with the tag on the display device, and selecting means for allowing the searcher to select an arbitrary searched character string registered in the tag displayed by the second display means. When,
And a search unit that searches the storage device for data specified by the search character string selected by the selection unit.

[0008]

In the data search method of the present invention, if a search character string that is often used is registered in advance in a plurality of frame-shaped tags displayed on the display device, the search character string is registered in the tag when searching for data. Since it is displayed in the same manner, it is possible to easily perform the same data search by using the same search character string many times by simply selecting the search character string in the displayed tag.

In the data search apparatus of the present invention, the first display means displays a plurality of frame-shaped tags on the display device. The registration unit registers an arbitrary search character string in an arbitrary tag among the plurality of tags displayed on the display device by the first display unit. The second display means displays the search character string registered in the tag by the registration means together with the tag on the display device during the data search. The selection means allows the searcher to select an arbitrary search character string registered in the tag displayed by the second display means. The search means searches the storage device for data specified by the search character string selected by the selection means. Thereby, the same data search can be easily performed only by selecting the same search character string as the previous time by the selecting means.

An external storage device control unit for controlling writing / reading of data to / from 2 is an external storage device such as a floppy disk or a hard disk in which data to be searched is stored.

The input device 5 is a tablet and the display device 7
In the case of LCD, these may be integrated to form an input display device, and information may be handwritten on the tablet with a stylus pen or the like.

Next, the operation of this embodiment will be described. First, the user performs an operation of preliminarily registering in a tag keywords and search conditions that are often used for searching data stored in the external storage device 12. Therefore, the user operates the input device 5 to set the CPU 1 in the search character string registration mode. As a result, the CPU 1 displays the registration screen as shown in FIG. 3 on the display device 7 via the display control unit 6 in step 201 shown in FIG. The screen shown in FIG. 2 is a screen on the input display device in which the input device 5 is a tablet and the display device 7 is integrally laminated under the tablet, and the registration information is displayed on the tablet with a stylus pen (not shown). Shall be written.

The user inputs frequently used keywords and search conditions in the search character string input frame 50 in the registration screen shown in FIG. 3, and then presses the confirmation button 51 to input the keywords or search conditions into the apparatus. . In response to this, the CPU
In step 1, the keyword or search condition input from the input device 5 via the input control unit 4 in step 202 is temporarily stored in the RAM.
It is stored in a predetermined area 2 and displayed on the display device 7 via the display control unit 6. At the same time, the CPU 1 determines in step 203 whether the keyword or the search condition has been input.
Returning to step 204, if completed, the process proceeds to step 204. By inputting the above-mentioned keywords or search conditions, the display device 7 displays the keywords or search conditions as shown in FIG. In this example, 1 Tokyo 2 Ah? ? ?
3. Search conditions such as Keio Line and keywords are displayed.

Next, the user performs an operation of distributing the keyword or search condition input as described above to the tags T1 to T3 displayed in the lower part of the screen of FIG. This operation is performed by inputting the identification number of the tag to be distributed to each input search condition or keyword as shown in FIG. In this example, the search condition of Tokyo is the tag T1.
It has been shown to be allocated to, and so on. Upon receiving such an operation, the CPU 1 displays the identification number of the input tag in the horizontal frame 53 facing the corresponding keyword or search condition in step 204, and then the confirmation button 5
When 1 is pressed, the identification number of the input tag is input to RAM
The keyword or search condition stored in a predetermined area in 12 is registered, the character string of the keyword or search condition is displayed in the tag as shown in FIG. 4, and the process ends.

Next, the operation for searching the data in the external storage device 12 by the user using the keyword or the search condition registered in the tag as described above will be described with reference to the flowchart of FIG. When the user operates the input device 5 to put the CPU 1 in the data search mode, the CPU 1 displays a data search screen as shown in FIG. The user looks at the keyword or search condition in the tag displayed at the bottom of the data search screen shown in FIG. 6 (A), and selects the character string of the keyword or search condition to use using a stylus pen (not shown). To do.

In response to this, the CPU 11 makes a step 50.
The keyword or search condition selected by the user in 2 is read from the RAM 2 and a tag ("Tokyo" in this example) in which the selected keyword or search condition is registered as shown in FIG. After deleting part of the registered tags). Go to step 503. Next, CPU
1 reads one piece of data in the external storage device 12 in step 503. At that time, in step 504, it is determined whether or not the data to be read remains in the external storage device 12, and if not, the process is performed. Is completed, and if there is any, the process proceeds to step 505.

The CPU 1 uses the external storage device 12 in response to the keyword or search condition read in step 505.
Judge whether the data read from inside matches,
If they do not match, the read data is erased, and then the process returns to step 503. If they match, the process proceeds to step 506. The CPU 1 displays the data read from the external storage device 12 in step 506 as matching the keyword or the search condition as shown in 23 of FIG. 6A, and then returns to step 503. The CPU 1 performs the processing of steps 503 to 506 for all the data in the external storage device 12 one by one, and then ends the search processing.

FIG. 6A is an example of a data search screen displaying the result of searching the data in the external storage device 12 using the search condition "Tokyo". FIG. 6B shows "A ????". 9 is an example of a data search screen displaying the result of searching the data in the external storage device 12 using the keyword. or,
In FIG. 6C, instead of the search condition “A ???”, a search condition “within 30 minutes” is newly registered, and the external storage device 1 is used by using the search condition “within 30 minutes”.
3 is an example of a data search screen displaying the results of searching the data in 2.

After that, when the user wants to perform a data search using the same search conditions as the previous time, for example, "Tokyo", the user is registered in the tag in the data search screen as shown in FIG. 6 (A). If you select "Tokyo" in the list again with a stylus pen, the data search process shown in Fig. 5 will be started.
The same search result can be obtained as shown in FIG.

According to this embodiment, when searching the data in the external storage device 12, the keyword or the search condition registered in the tag is used, and the keyword or the search condition once used is the tag. Since it is still registered above, if you want to search the data again using the same keyword or search condition, use the same keyword or search condition that was used last time displayed on the screen. By simply selecting, you can perform a data search with the same search character string as the previous time, significantly simplifying the user's operation at the time of data re-search using the same keyword or search condition as the previous time and improving operability. Can be improved.

Moreover, since the keyword or search condition used last time is displayed as it is registered in the tag, it is impossible to forget the keyword or search condition used last time and perform a data search with the same search character string. Can be eliminated.

When searching for data using the same keyword or search condition as the keyword or search condition used last time on the same screen, a part of the tag of the keyword or search condition used last time is used. Since it is deleted, you can immediately know which keyword or search condition you used last time, but when you turn off the power and operate the device again, the keyword or search condition used last time By deleting and displaying a part of the registered tag, the user can definitely know the keyword or the search condition used last time. Further, in the above embodiment, the case where the search character string is registered in three tags has been described, but the case where there are four or more tags is the same, and the same effect is obtained.

FIG. 7 is a diagram showing an example of a data search screen showing another embodiment of the present invention. In this example, the search string is
When "Tokyo" is selected first, the narrowing-down button 61 is further pressed, and then "A ????" is selected to search for data, the CPU 1 displays both "Tokyo" and "A ???". The common (logical product condition) search data is searched from the external storage device 12, and the search result (in this example, Akabane) is displayed as shown in FIG.

As yet another embodiment, by pressing the narrow-down button 61 each time a search character string is selected,
A search corresponding to a logical product condition or a logical sum condition of three or more search character strings can be performed in the same manner as above.

[0025]

As described above, according to the data search method and the data search apparatus of the present invention, the operation for re-searching data using the same keyword or the same search condition is simplified and the same as the previous time. You can search again with the keywords or search conditions.
