Abstract

PURPOSE: To enable a user to easily retrieve data and to improve the usability by visually displaying the amount of sorted data at the time of data retrieval. CONSTITUTION: Object data to be retrieved are rearranged by a data sorting part 16. Then, a retrieval point display part 17 displays a retrieval point corresponding to the amount of data to be retrieved. An event generated next by an input device is expected and when the event specifies the retrieval point, the event is passed to a data conversion part 18 to find the index of sort data from the event generation place, thereby displaying the data on the basis of the index. Thus, when the data is retrieved, the amount of data which are sorted is visually represented and then data retrieval by human presumption can easily be performed, thereby improving the usability.

Description

Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention makes it easy for a user to make a data search by guessing, by sorting by a key of search when searching data and expressing the search points by a continuous amount on the screen. The present invention relates to a data search device.

[0002]

2. Description of the Related Art Conventionally, when searching for data, for example, desired data is searched by narrowing down with a specific key.

[0003]

However, in the above-mentioned conventional method, the data must be accurately narrowed down, and the operation is complicated. Moreover, it was difficult to perform an ambiguous search.

Therefore, the present invention has been made in consideration of the above circumstances, and when a data search is performed, the user can easily search the data by visually expressing the sorted data amount. It is an object of the present invention to provide a document creation device which is improved in usability.

[0005]

In order to achieve the above object, the present invention provides a data search in which data amount of search target data is expressed on a screen of a display device (for example, in the data amount). Depending on the file display, the thickness changes)
A search point display means capable of displaying, an input means for instructing a portion expressing the data amount of the displayed data (by a pointing device such as a mouse), and a data point from the instructed point. A data search processing device comprising: a data conversion unit that returns which part to the requesting device to facilitate a data search by guessing.

In order to achieve the above object, the present invention provides the above data search processing device with a data sorting means for sorting data by a specific key (last access time, document name, etc.), It is possible to search data by guess other than the order of stored data.

Further, in order to achieve the above object, the present invention provides an expression capable of identifying a certain key adjacent to a certain specific key when displaying a search point in the data search processing device. I have decided to do it.

Further, in order to achieve the above object, the present invention provides
In the above data search processing device, when displaying the search points, the display is performed by changing the color according to the classification different from the search key which is the current sort target.

[0009]

In the above structure, when the data retrieval is performed, the sorted data amount is visually expressed, and the user can easily retrieve the data.

[0010]

The outline of the apparatus according to the present invention is as follows. That is, as a first point, in a device that searches for certain data, a search point display device that can display a data amount of the search target data on the screen, and a thickness expression of the displayed data. By providing an input device capable of instructing a part and a data conversion device for returning to the requesting device which part of the data sorted from the instructed point, it is possible to facilitate the data retrieval by guessing.

Next, as a second point, in the above-mentioned first point apparatus, by providing a data sorting apparatus for sorting data by a specific key (last access time, document name, etc.), It is to be able to easily perform data retrieval by guess other than the order of stored data.

As a third point, in the above-mentioned second point device, when a search point is displayed, a certain key can be expressed so as to identify adjacent ones in the same category. By providing the search point display device, the above data search can be performed more easily.

Further, as the fourth point, in the above-mentioned first point, second point or third point, when the search points are displayed, the search key which is the current sort target. According to another classification, a search point display device capable of displaying in different colors is provided to facilitate the search.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of one embodiment of the present invention. In FIG. 1, reference numeral 10 denotes a microprocessor (CPU), which controls various controls of the entire system and the controls shown in FIGS.

Reference numeral 11 is a ROM (storage device, read-only memory) which stores program information and various fixed data required by the CPU 10. Reference numeral 12 denotes a RAM (storage device, readable / writable memory) for storing various data works and program information.

Reference numeral 13 is a search data storage section which is a storage device for storing search data. An input control unit 14 controls input from an input device (not shown) such as a keyboard and a mouse.

A display device 15 is a CRT or LCD.
And its control device, and displays and outputs various data. 16 is a data sort unit,
The search data is sorted under the control of the CPU 10.

A search point display unit 17 is a control unit for displaying the sorted data on the display device 15. Reference numeral 18 is a data conversion unit for returning an index from the input from the input device (not shown) to the data sorted by the data sorting unit 16.

2 is a flow chart showing the overall flow of this embodiment, and FIG. 4 is a flow chart showing the flow of the data conversion section 18. FIG. 3 is a conceptual diagram for explaining the conceptual operation of the flow of the data conversion unit 18 in the above embodiment.

The operation of the above structure will be described below. First, the data to be searched is sorted by the data sorting unit 1
The data is rearranged by 6 (see step S21 in FIG. 2). Next, the search points are displayed by the search point display unit 17 in a form corresponding to the amount of data to be searched (step S22 in FIG. 2). An input device (not shown) waits for an event to occur next (step S23 in FIG. 2). If the event is an event that specifies a search point, the event is passed to the data conversion unit 18 and the sort data is generated from the event occurrence location. To obtain the index of (Fig. 2
Step S24). An application using the present invention will display data based on this index.

By the way, the data converter 18 is activated when an event designating a search point occurs, and first checks whether the event occurrence location is within the search point input range (step of FIG. 4). S41).

If it is not within the range (N in step S41 of FIG. 4), the process is terminated. If it is (Y in step S41 of FIG. 4), how far the event occurrence location is from the origin of the input range is obtained (step S42 of FIG. 4). Then, the index is obtained according to how much of the obtained distance occupies the whole (step S of FIG. 4).
43).

[0023]

As described above in detail, according to the present invention, when a data search is carried out, the amount of sorted data is visually expressed, thereby facilitating the data search by a human guess. Therefore, it has an excellent effect that the usability can be improved.
