Including the execution of. The searched data includes at least character string data used for searching. The character string data may be included in the searched data in a mode (so-called plain text or the like) in which the searched data itself is a set of character string data, or in a mode (metadata or the like) associated with the searched data. It may be included. Further, the character string data may be included in the search target data in a manner in which a known compression process or encryption process is performed.

In the present embodiment, it is assumed that the data search device 100 is a personal computer, and the display device 200 is portable electronic paper. The display device 200 is connected to the data search device 100 when the search processing by the data search device 100 is executed. In other cases, the display device 200 is used independently of the data search device 100. In addition, it is assumed that the search target data of the present embodiment is document data representing displayed characters and images.

The data search apparatus 100 includes a control unit 110, a storage unit 120, a communication unit 130, an operation unit 140, and a display unit 150. The control unit 110 is a CPU (Central Processing Uni
t) and the like, and an operation of the data search device 100 is controlled by executing a program stored in advance. The program executed by the control unit 110 includes a program that realizes a search process described later. The storage unit 120 includes a rewritable nonvolatile memory and stores various types of data including data to be searched. Communication unit 130
Is connected to the communication unit 230 of the display device 200 and transmits and receives data. The connection by the communication unit 130 may be either wired or wireless. The operation unit 140 includes an input device such as a keyboard and receives an operation by a user. The operation unit 140 generates operation information representing a user operation and supplies the operation information to the control unit 110. The user's operation includes setting search conditions. The display unit 150 includes a display device and displays an image according to an instruction from the control unit 110. The display unit 150 displays an image for the user to check search conditions and search results.

The display device 200 includes a control unit 210, a storage unit 220, a communication unit 230, and an operation unit 240.
And a display unit 250. The control unit 210 has the same configuration as that of the control unit 110 of the data search apparatus 100. However, in this embodiment, it is assumed that the control unit 210 is inferior in arithmetic processing capability to the control unit 110 for convenience of explanation. The storage unit 220 includes a rewritable nonvolatile memory and stores various types of data including data to be searched. The communication unit 230 is a communication unit corresponding to the communication unit 130 of the data search apparatus 100 and transmits / receives data to / from the communication unit 130. The operation unit 240 includes an operation element (button or the like) for selecting data to be searched or a folder to be described later, and generates operation information indicating a user's selection operation and supplies the operation information to the control unit 210.
The display unit 250 includes a display panel and a drive circuit that drives the display panel, and displays a search result by search processing and a document represented by search target data.

The display panel of the display unit 250 of the present embodiment is preferably a display panel using a memory display. Here, the memory property indicates a gradation corresponding to a voltage when a voltage is applied, and a display that maintains the displayed gradation even in a state where the voltage is not applied after the voltage is applied. It refers to the properties of the body and is also referred to as bistability or non-volatility. As the memory display body, for example, a display body using an electrophoretic element or a cholesteric liquid crystal can be used. When a memory-type display is used for the display unit 250, it is not necessary to apply a voltage while the same image is displayed, and thus power consumption may be suppressed.

The storage units 120 and 220 may include a storage area that can be attached to and detached from the data search device 100 or the display device 200 like so-called memory cards. In this way, the memory card attached to the display device 200 is taken out and the data search device 100 is removed.
The data to be searched can be supplied and acquired without communication by the communication units 130 and 230.

The configuration of the data search system 10 of this embodiment is as described above. With this configuration, the display device 200 is used for a user to browse a document. The user selects document data to be browsed (that is, data to be searched) before browsing the document. Display device 20
The selection method of data to be searched at 0 includes a method of selecting data to be searched from a list of data to be searched and a method of using a search result generated by the data search device 100.

FIG. 2 is a diagram illustrating data stored in the storage unit 220 of the display device 200. As shown in the figure, the storage unit 220 has a document area Ar1 and a search folder area Ar2 as storage areas. The document area Ar1 is a storage area allocated in advance for storing document data. The search folder area Ar2 is a storage area allocated for displaying the search results, and is a storage area in which link information for identifying the document data stored in the document area Ar1 is described in a hierarchical structure. The hierarchical structure here is a directory for classifying data, and generally each hierarchy is distinguished by a folder (image).
The link information is an example of identification information in the present invention, and is data describing the location of document data (address in the document area Ar1). Hereinafter, a set of link information having such a hierarchical structure is referred to as a “search folder”. That is, the search folder is a group of data obtained by collecting a plurality of link information using a hierarchical structure.

The search folder is generated by the data search device 100 and supplied to the display device 200. In order to generate a search folder, the data search device 100 acquires document data stored in the display device 200, and extracts character string data from the acquired document data. When a user of the display device 200 wants to obtain a search folder (that is, a search result), the display device 200 is connected to the data search device 100 and a search condition is input using the data search device 100.

FIG. 3 is a functional block diagram illustrating functions realized by the control unit 110 of the data search device 100 when a search folder is generated. The control unit 110 implements functions corresponding to the data acquisition unit 111, the condition specifying unit 112, the search unit 113, the generation unit 114, and the supply unit 115 by executing a program.

The data acquisition unit 111 has a function of acquiring document data that is data to be searched. In this embodiment, the data acquisition unit 111 acquires from the display device 200 via the communication unit 130. Note that the document data need not be deleted from the display device 200 because the document data need only be copied. Further, the path of document data acquisition by the data acquisition unit 111 is not limited to this, and may be from the storage unit 120 of the own apparatus. For example, the data acquisition unit 111 can also acquire document data from the memory card portion of the storage unit 120.

The condition specifying unit 112 has a function of specifying a search condition for document data. put it here,
The search condition refers to a condition relating to a search folder to be generated, and includes at least character string data. The search condition may include, for example, time information (creation date, last update time, etc.) associated with the document data and attribute information (extension, etc.). In this way, it is possible to narrow down (that is, limit) the document data to be searched. When the document area Ar1 has a hierarchical structure, a search condition for searching for any one of the hierarchical structures may be provided.

In the present embodiment, the search condition is input by the user via the operation unit 140. At this time, the condition specifying unit 112 specifies the search condition based on the operation information from the operation unit 140. Note that the search condition may be acquired together with the document data via the storage unit 120 or the communication unit 130.

In addition, the search condition of this embodiment includes a mode in which character string data is designated by so-called AND search. That is, the search condition of this embodiment specifies a plurality of search conditions,
It may be for extracting document data satisfying all of them as a search result. For example, the search condition in the present embodiment may specify a first character string “abc” and a second character string “xyz”, and extract document data including both, Document data including the column “abc” and having a last update time after a predetermined time may be extracted.

When there are a plurality of search conditions, the condition specifying unit 112 can specify a combination based on the plurality of search conditions. For example, the condition specifying unit 112 uses the first character string “abc” and the second character string
When two types of search conditions of the character string “xyz” are designated, the “first” including the first character string
Search condition ”and“ second search condition ”including the second character string, and“ third search condition ”including the first character string and the second character string are specified as the search conditions. obtain. The third search condition is
The search condition is a combination of the first search condition and the second search condition. Hereinafter, the search condition based on such a combination is also referred to as “combination condition”.

In other words, the condition specifying unit 112, when n types of search conditions are specified, at most,
N types of search conditions that satisfy 1) are specified. Here, “ _n C _m ” represents the number of combinations for selecting different m items from different n items. Note that the number of search conditions specified by the condition specifying unit 112 need not be all possible combinations, and may be less than the value of N.

The search unit 113 uses the condition specifying unit 11 from the document data acquired by the data acquisition unit 111.
2 has a function of searching for document data corresponding to the search condition specified by 2. Search unit 11
Any known method may be adopted as the search method according to 3, for example, a so-called grep type or index (index) type may be used. That is, the search unit 113 may sequentially search each document data as necessary, or may create an index that assists the search in advance and search using this index.

The generation unit 114 has a function of generating link information of document data searched by the search unit 113. When there are a plurality of search conditions specified by the condition specifying unit 112, the generation unit 114 generates link information corresponding to each of the plurality of search conditions. In addition, when there are a plurality of search conditions including combination conditions, the generation unit 114 generates link information with a hierarchical structure.

The supply unit 115 has a function of supplying the link information generated by the generation unit 114 to the display device 200 as a search folder. The supply unit 115 supplies the link information generated by the generation unit 114 in association with the search condition used for the search by the search unit 113. When the search folder of the present embodiment is used, the search condition is associated with the link information as the name of the folder (that is, each hierarchy).

FIG. 4 is a flowchart showing search folder generation processing by the control unit 110 of the data search apparatus 100. As shown in the figure, first, the control unit 110 determines whether or not communication with the display device 200 is possible (step S1). Note that the control unit 110 includes the display device 20.
Instead of the connection of 0, it may be determined whether or not generation of a search folder is instructed via at least one of the operation units 140 and 240. If the control unit 110 cannot communicate with the display device 200, the control unit 110 cannot acquire the document data, and therefore does not execute the processes after step S2.

When communication with the display device 200 becomes possible, the control unit 110 acquires document data from the display device 200 (step S2), and then specifies a search condition (step S3). Note that the order of the process of step S2 and the process of step S3 may be reversed. That is, the user
Search conditions may be input before connecting the data search device 100 and the display device 200.

When the document data and the search conditions are prepared, the control unit 110 searches for the document data corresponding to the search conditions using any of the specified search conditions (step S4). Control unit 1
When the document data corresponding to the search condition is found, 10 generates link information related to the document data (step S5). Further, the control unit 110 determines whether or not the search has been executed for all the specified search conditions (step S6), and if there is a search condition for which the search has not been executed, the search conditions in steps S4 to S6 are determined. Repeat the process.

Finally, the control unit 110 generates a search folder based on the link information generated in step S5, and supplies it to the display device 200 via the communication unit 130 (step S).
7). In the display device 200, the search folder is stored in the search folder area Ar2. Note that when the search folder supply is completed, the data search device 100 or the display device 200 may notify the fact by an image or sound. When the user confirms that the search folder has been generated on the display device 200, the data search device 100 and the display device 200 are displayed.
Can be removed and the display device 200 can be carried.

FIG. 5 is a diagram illustrating a display mode of the search folder. FIG. 6 is a diagram showing the association between link information and document data in the example of FIG. In this example, the name of the folder corresponds to the search condition. At this time, displaying the link information included in the folder indicates that the link information is a search result corresponding to the search condition represented by the folder.

FIG. 5A is a diagram showing link information included in a folder whose name is “abc” and folders corresponding to the lower layers of the folder. In this example, the link information “link
“_data1” indicates that the corresponding “data1” includes the character string “abc”. The link information “link_data2” indicates that the corresponding “data2” includes the character string “abc”. When the user selects any of these link information with a cursor (not shown), the corresponding document data can be displayed on the display unit 250. The link information may be displayed as characters such as “link_data1” in the figure, or may be displayed as an image such as a so-called icon.

The folder “abc & xyz” indicates that the link information of the document data including the character string “abc” and the character string “xyz” is described in the hierarchy corresponding to this folder. Is. When the user selects this folder “abc & xyz”, the display device 200 switches the display from FIG. 5A to FIG. 5B. In the example of FIG. 5, “data1” includes both “abc” and “xyz”, but “data2” includes “xyz”.
"Is not included, and only" abc "is included.

As described above, according to the data search system 10 of the present embodiment, the search result can be used on the display device 200 without executing the search process. That is, in the display device 200 of this embodiment, as long as there is a function for recognizing and displaying the association by the link information,
Even if the document data search process is not executed, it is possible to select and display document data corresponding to a desired search result.

Further, according to the display device 200 of this embodiment, by using the search folder, the search result can be used while maintaining the data structure of the previous document data without moving the existing document data. . In addition, since the search folder describes not the document data itself but the link information of the document data, the document data is not duplicated, and the communication volume between the data search device 100 and the display device 200 can be suppressed. is there. Furthermore, if the search folder has a hierarchical structure, it is easy to narrow down search conditions.

[Modification]
The present invention can be implemented in a form different from the above-described embodiment. The following modifications are examples of modifications applicable to the present invention. The above-described embodiment and the following modification examples may be applied in combination as necessary.

(Modification 1)
The data search device of the present invention acquires search target data stored in the storage unit of the data search device in addition to the search target data acquired from the display device, and performs search processing based on both search target data. Also good. Here, the storage unit of the data search device is not limited to the storage medium included in the data search device, and may include a storage medium that is detachable from the data search device.

When this example is applied to the data search system 10 described above, the search result can be displayed also in the data search apparatus 100. Further, in the data search apparatus 100, the document data may be edited to rewrite the contents, or the document data may be deleted. If such editing or deletion is performed, the search result may be affected. Therefore, the data search apparatus 100 may perform a search process for each predetermined event or cycle, and rewrite the display contents of the search folder when a change occurs in the search result. In this way,
It is possible to display search results that are more realistic.

In addition, when including the document data stored in the storage unit 120 of the own device in the search result, the data search device 100 generates link information to the document data stored in the storage unit 120 of the own device. May be included in the search folder and supplied to the display device 200. In this case, the display device 200 can display the document data only when connected to the data search device 100. On the other hand, in order to be able to display the document data even when not connected to the data search device 100, the data search device 100 may be supplied with the document data.

FIG. 7 is a flowchart according to this example, and shows a process in which the data search apparatus 100 supplies a search folder and document data. In the figure, the same reference numerals are assigned to the steps for performing the processes common to the generation process (see FIG. 4) of the embodiment described above.
That is, in the processing according to this example, the step of acquiring the document data (step Sa1), the step of specifying the difference of the document data (step Sa2), and the step of supplying the search folder and the difference (step Sa3) are performed as described above. The form differs from the generation process.

In step Sa <b> 1, the control unit 110 acquires document data from the storage unit 120 of the data search device 100 in addition to the storage unit 220 of the display device 200. At this time, the control unit 11
If the document data not stored in the storage unit 120 is included in the document data acquired from the storage unit 220, the document data may be written in the storage unit 120. In this way, all the document data stored in the display device 200 can be stored in the data search device 100.

In step Sa2, the control unit 110 specifies document data that has not been acquired from the display device 200 among the document data searched in step S4. The document data specified here is hereinafter referred to as “(difference of document data)”. Step Sa3
The control unit 110 supplies the search folder and the difference to the display device 200.
Note that the difference supply mode is copying rather than moving document data. That is, the control unit 110 newly generates document data corresponding to the difference and supplies it.

When the operation is performed as described above, the display device 200 can use the search result based on the document data stored in the data search device 100 in addition to the search result based on the document data stored in the device itself. Become.

Note that the difference between the document data is not limited to the document data searched in step S4, and the document data not acquired from the display device 200 among all the document data stored in the data search device 100. May be supplied as a difference to the display device 200. In this way, all the document data stored in the data search device 100 can be stored in the display device 200.

(Modification 2)
In the first modification described above, the search folder stored in the data search apparatus 100 is a folder whose search results change according to the search target data stored in the self apparatus. Hereinafter, the display mode of such a folder is referred to as “dynamic” for convenience. On the other hand, the search folder stored in the display device 200 is a folder whose search result does not change unless it is updated by connecting to the data search device 100. Hereinafter, such a folder mode is referred to as “static” for convenience.

In the present invention, the dynamic or static distinction in the search folder can be determined based on the suitability of execution of the search process. For example, in a display device (for example, the display device 200) that does not have enough hardware resources to execute the search process, the search folder is static and the display device has hardware resources sufficient to execute the search process. (Display device 2
In a display device different from 00), the search folder is dynamic. In order to realize such distinction, for example, a function for determining a display device to which a search folder is supplied may be given to the data search device.

FIG. 8 is a functional block diagram according to the present example, which is a modification of the control unit 110 (see FIG. 3) of the above-described embodiment. The control unit 110a according to this example includes the determination unit 116 and the supply unit 11.
Except for 7, the configuration is the same as that of the control unit 110 shown in FIG. The determination unit 116 has a function of determining the connected display device. The determination by the determination unit 116 may be to directly determine the hardware resources of the display device, but data (version information or the like) indicating the performance of the display device is stored in the display device in advance and is read out. It may be discriminated by the above.

The supply unit 117 has a function of changing the supply mode of the search folder according to the determination result by the determination unit 116 when supplying the link information generated by the generation unit 114 to the display device 200 as a search folder. The aspect here may be a predetermined one, for example, the presence or absence of a flag for identifying whether the search folder is dynamic or static. That is, the supply unit 117 may supply the search folder in such a manner that the display device can recognize the dynamic search process when the display device to which the connection is made executes dynamic search processing.

(Modification 3)
The search condition in the present invention may not be based on user input. For example, the search condition may be one in which characters are selected in a predetermined order such as alphabetical order or alphabetical order, or may be extracted according to search target data to be searched. For example, it is possible to extract a character string from a plurality of data to be searched for in units of words, and use a predetermined number of words extracted relatively frequently as a search condition. In this way, the search folder can be used as an index of searched data.

(Modification 4)
The combination condition in the present invention is not limited to AND search as in the above-described embodiment, but may be so-called OR search. That is, the “combination” of search conditions in the present invention
May be either a logical product (AND) or a logical sum (OR) in a logical operation, or may be further combined with negation (NOT). For example, the combination condition in the present invention may be “includes the first search condition and does not include the second search condition”.

(Modification 5)
The present invention can also be provided as a program for causing a computer to realize the functions of the control unit 110 described above. Such a program may be provided in a form recorded on a recording medium such as an optical disk or a flash memory, or in a form downloaded to a data search device via a network such as the Internet.
