Here, the cursor moves from day to day. That is, the cursor indicates another date by the operation of the operation unit 18. Thereby, one or a plurality of data associated with the date is identified and displayed. In the state of FIG. 2, when the date on which the characters “16:00 Customer A” are displayed is indicated by the cursor, the schedule data of “16:00 Customer A” associated with the date is identified and displayed. . The data search apparatus 10 measures the time for which data is continuously identified and displayed by the cursor, and monitors whether the time exceeds a predetermined time. When the time for which the identification display is continued exceeds a predetermined time, the search keyword is extracted from the data identified and displayed by the cursor, and the data including the search keyword is searched from the storage unit 12.

  FIG. 3 shows a data search screen after the search processing by the search keyword “customer A” extracted from “16:00 customer A” displayed in FIG. 2 is completed. As shown in the figure, in this screen, the same image as the image displayed in the application display area 42 of the data search screen shown in FIG. On the other hand, a search result icon (image) 44 is displayed in the search result display area 40. The search result icon 44 is displayed in association with one or a plurality of data including the search keyword “customer A”. Specifically, among the data including the search keyword “customer A”, data associated with the common application program are collected, and one search result icon 44 is displayed in the search result display area 40 for the data. It is like that. Here, it is shown that data associated with three application programs has been found by a search. That is, the search result icon 44 in which the character “A” is represented is associated with data associated with the schedule management program among the data including the search keyword “customer A”. In addition, the search result icon 44 in which the character “C” is represented is associated with data associated with the e-mail transmission / reception program among the data including the search keyword “customer A”. Further, the search result icon 44 representing the character “B” is associated with data associated with the memo pad program among the data including the search keyword “customer A”.

  When the user taps the search result icon 44 in which the character “A” is displayed on the data search screen shown in FIG. 3, the data search screen shown in FIG. 4 is displayed. That is, when the user taps the search result icon 44 in which the character “A” is displayed on the data search screen shown in FIG. 3, a search associated with the search result icon 44 is displayed in the application display area 42. Data including the keyword “customer A” is displayed by the schedule management program. In this case, the application program that displays an image in the application display area 42 remains the schedule management program, and the data (date) identified and displayed by the cursor is the source of the search keyword “customer A”. It is.

  In FIG. 4, the cursor is moved by the operation of the operation unit 18, the data to be identified and displayed is changed from the schedule data of “16:00 Customer A” to the schedule data of “13:00 Customer A Customer B”, When the time continuously displayed for identification exceeds a predetermined time, the search keywords “customer A” and “customer B” are extracted from the schedule data “13:00 customer A customer B”, and the search keyword “customer A” is extracted. Alternatively, data including “customer B” is retrieved from the storage unit 12. That is, an OR search is performed. After the search is started, the search result display area 40 once returns to the blank as shown in FIG.

  FIG. 6 shows a data search screen after the search processing by the search keywords “customer A” and “customer B” extracted from the schedule data “13:00 customer A customer B” displayed in FIG. Yes. As shown in the figure, in this screen, the same image as the image displayed in the application display area 42 of the data search screen shown in FIG. On the other hand, a search result icon 44 and a return icon (image) 45 are displayed in the search result display area 40. The search result icon 44 is displayed in association with one or a plurality of data including the search keyword “customer A” or “customer B”. Specifically, among the data including the search keywords “customer A” or “customer B”, data related to the common application program are collected, and one search result icon 44 is displayed for the search data in the search result area 40. Is displayed. Here, it is shown that data associated with three application programs has been found by a search. That is, the search result icon 44 in which the character “A” is represented is associated with data associated with the schedule management program among the data including the search keyword “customer A”. Further, the search result icon 44 in which the character “C” is represented is associated with data associated with the memo pad program among the data including the search keyword “customer A”. In addition, the search result icon 44 in which the character “B” is represented is associated with data associated with the e-mail transmission / reception program among the data including the search keyword “customer A”. The return icon 45 is an icon for returning the display of the search result display area 40 before executing the search. When the return icon 45 is tapped, the screen may be returned in units of operations, or the screen may be returned in units of search (that is, the screen returns to the screen immediately after the previous search process). You may do it). In this case, only one or both of the search result display area 40 and the application display area 42 may be returned.

  When the user taps the search result icon 44 in which the character “A” is displayed on the data search screen shown in FIG. 6, the data search screen shown in FIG. 7 is displayed. That is, when the user taps the search result icon 44 in which the character “A” is displayed on the data search screen shown in FIG. 3, a search associated with the search result icon 44 is displayed in the application display area 42. Data including the keyword “customer A” or “customer B” is displayed by the schedule management program. In this case, the application program for displaying an image in the application display area 42 remains the schedule management program, and the data (date) identified and displayed by the cursor is extracted from the search keywords “customer A” and “customer B”. It is the original one.

  On the other hand, when the user taps the search result icon 44 in which the character “C” is displayed on the data search screen shown in FIG. 6, the data search screen shown in FIG. 8 is displayed. That is, as described above, the search result icon 44 in which the letter “C” is represented corresponds to the data associated with the e-mail transmission / reception program among the data including the search keyword “customer A” or “customer B”. It is attached. Therefore, when the user taps the search result icon 44, the e-mail transmission / reception program is started and data associated with the search result icon 44 is displayed. In this case, since the application program for displaying an image in the application display area 42 is changed, the cursor position is set to a predetermined position (for example, the uppermost part or the upper left part of the application display area 42).

  In this data search apparatus 10, the search result already searched is diverted to reduce the data search processing. For example, in the data search screen shown in FIG. 5, the search keywords “customer A” and “customer B” are extracted from the schedule data “13:00 customer A customer B”, and the search keywords “customer A” or “customer B” are extracted. When the data including the search keyword “customer A” has already been searched, the data including the search keyword “customer B” is searched and the search keyword “customer A” is searched. The data search screen shown in FIG. 6 is promptly displayed by diverting the search results that have already been obtained for the data including “”. That is, among the data shown on the data search screen in FIG. 6, data including the search keyword “customer A” is based on the search results already obtained when the data search screen shown in FIG. 4 is displayed. It is identified and displayed on the data search screen of FIG. On the other hand, data including only the search keyword “customer B” has been found by a new search process. Therefore, in the application display area 42, for example, the display mode such as color, blinking presence / absence, blinking speed, etc. is changed between the data found by the new search and the data found by the previous search. A character or background may be displayed.

  In the data search screen shown in FIG. 7, even when the cursor moves to the schedule data “10:00 customer B” and the search keyword “customer B” is extracted, the data including the search keyword “customer B” Since the search has already been performed, the data search screen is updated without diverting the search and performing the actual search process.

  FIG. 9 is a functional block diagram of the data search apparatus 10. In the figure, among the functions realized by the data search device 10, those related to the present invention are mainly shown. These functions are realized by the control unit 14 executing the data search program stored in the storage unit 12.

  As shown in the figure, the functions implemented by the data search apparatus 10 include a data storage unit 22, a search unit 24, a search management unit 26, a search keyword extraction unit 28, a selection data determination unit 30, and a search result storage unit. 32, a search history storage unit 34, an icon UI unit 38, and an application control unit 36 are included.

  The data storage unit 22 includes the storage unit 12 and stores data associated with various application programs. Here, a plurality of schedule data associated with the schedule management program, a plurality of e-mail data associated with the e-mail transmission / reception program, a plurality of memo pad data associated with the memo pad program, and a plurality of associated with the handwritten memo program Handwritten memo data, a plurality of address book data associated with the address book management program, and the like are stored. Each data need not be stored in file units, and may be a part of one file. One data may be constituted by a plurality of files.

  The selection data determination unit 30 examines data indicated (identified and displayed) by the cursor among data displayed in the application display area 42 by the application program. Then, it is monitored whether or not the instruction from the cursor is continued for a predetermined time or more with respect to the same data. Notify There may be one or more data to be notified at this time.

  The search keyword extraction unit 28 extracts a search keyword from the data thus notified. Specifically, each type of data stored in the data storage unit 22 is composed of one or a plurality of items, and the search keyword extraction unit 28 uses data associated with the application program for each application program. When extracting a search keyword, data specifying from which item the search keyword is extracted is stored in advance. Then, the search keyword extraction source is specified according to this data. For example, the schedule data associated with the schedule management program is composed of items such as a title, a place, a memo, and a date, and the title, location, and memo items are stored as search keyword extraction sources. In addition, the e-mail data associated with the e-mail transmission / reception program is composed of a subject, a sender, a destination, a body, and the like, and items of the subject, the sender, and the destination are stored as search keyword extraction sources. . The address book data associated with the address book program consists of name, email address, address, company name, company address, memo, phone number, postal code, etc., of which name, email address, address, company name Company address and memo are stored as search keyword extraction sources. Further, the handwritten memo data associated with the handwritten memo program is composed of the image itself and the file name, and both of them (the search keyword is extracted by character recognition for the former) are stored as the search keyword extraction source. .

  The search keyword extraction unit 28 also stores a search prohibition word. The search prohibition word is stored in association with a combination of application program and data items. For example, with respect to the schedule management program, among the items of the schedule data, “meeting”, “meeting”, “drinking party”, etc. are stored as search prohibited words in association with the title. In addition, among the items of the schedule data, “conference room ○”, “meeting room ○”, “No. ○ reception”, etc. are stored as search prohibited words in association with the place.

  When the notification of the data for extracting the search keyword is received from the selected data determination unit 30, the search keyword is extracted from which of the items constituting the data, and the search keyword is extracted by a known method. . At this time, when a search prohibited word stored in advance is extracted, the search keyword is discarded. Then, the remaining search keywords are notified to the search management unit 26. The search keyword extraction unit 28 may store a plurality of items for extracting the search keyword. In this case, it is preferable to determine from which item the search keyword is extracted according to the type of operation performed on the operation unit 18. For example, the search keyword may be extracted from different items according to the number of times the display unit 16 is tapped. If the time identified and displayed by the cursor exceeds a predetermined time, a search keyword is extracted from the first item of the data to be identified and displayed before the time identified and displayed by the cursor exceeds the predetermined time. When the display unit 16 is tapped, a search keyword may be extracted from a second item different from the first item from the data displayed at the tapped position.

  The search management unit 26 checks the search keyword notified from the search keyword extraction unit 28, and checks whether there is any search keyword that has already been searched by referring to the stored content of the search history storage unit 34. . If the search keyword that has already been searched is not included, the search keyword is notified to the search unit 24. On the other hand, if a search keyword for which the search has been completed is included, only the remaining search keywords (for which the search has not been completed) are notified to the search unit 24. The search unit 24 searches the data stored in the data storage unit 22 for data including the search keyword notified from the search management unit 26. And the data (specific data) which specify the data containing a search keyword are produced | generated. The specific data is written in the search result storage unit 32 as an icon information list to be described later for each search process. Further, the data (name of an icon information list to be described later) written in the search result storage unit 32 for each search process and the search keyword used for the search process are associated with each other by the search unit 24. And stored in the search history storage unit 34.

  10 to 12 are diagrams illustrating examples of icon information lists stored in the search result storage unit 32. FIG. 13 is a diagram illustrating an example of a search history list stored in the search history storage unit 34.

It is a thing. Further, the icon information list shown in FIG. 11 uses the search keyword “customer B” among the search keywords “customer A” and “customer B” when the data search screen shown in FIG. 6 is displayed. Is written in the search result storage unit 32 by the search unit 24. The icon information list shown in FIG. 12 is the icon information list shown in FIG. 10 and the icon shown in FIG. 11 stored in the search result storage unit 32 when the data search screen shown in FIG. 6 is displayed. The search management unit 26 generates the information list by combining the information lists, and the search management unit 26 writes the information list in the search result storage unit 32. As shown in these figures, in the icon information list, an icon ID for specifying the search result icon 44, and specific data for specifying data found by the search (in this case, described as a database name and a record number) The type of application for displaying the data specified by the specific data is stored in association with each other.

  On the other hand, the search history list stored in the search history storage unit 34 shown in FIG. 13 includes data (selection data) for specifying data from which search keywords are extracted, a search keyword extracted from the data, Data (name of icon information list) for specifying an icon information list in which a search result based on the search keyword is recorded is stored in association with each other. By the combination of the search result storage unit 32 and the search history storage unit 34, the data search apparatus 10 stores the search keyword and the data specifying the data including the search keyword in association with each other.

  When the search keyword is notified from the search keyword extraction unit 28, the search management unit 26 matches the search keyword included in the search history list stored in the search history storage unit 34 among the notified search keywords. Check if there is any. If there is such a search keyword, the remaining search keywords are notified to the search unit 24 except for the matched search keyword. If there is no match, the search unit 24 is notified of all search keywords. If there is a search keyword that matches the search keyword included in the search history list, the search unit 24 writes the icon information list in the search result storage unit 32 based on the search results using the remaining search keywords, and the search history The list will be written. In this case, the search management unit 26 searches the search keywords notified from the search keyword extraction unit 28 for the search keywords that are not notified to the search unit 24 because they match the search keywords included in the search history list. The name of the icon information list generated at the time of searching using a keyword and written in the search result storage unit 32 is read from the search history list. Then, the icon information list is read from the search result storage unit 32. Furthermore, the search unit 24 reads the icon information list written in the search result storage unit 32 based on the search results using the remaining search keywords. Then, the two lists are combined to generate a new icon information list, which is written in the search result storage unit 32. In addition, data corresponding to the icon information list is written in the search history storage unit 34. That is, all the search keywords notified from the search keyword extraction unit 28 (including both of the notifications notified to the search unit 24 and those not notified) and the name of the newly generated icon information list are associated with each other. Write.

  The icon UI unit 38 generates an image of the search result display area 40 of the data search screen based on the icon information list stored in the search result storage unit 32, and displays and outputs it. Further, it is monitored that any one of the search result icons 44 is tapped. When tapped, the specific data and application stored in the icon information list in association with the icon ID of the tapped search result icon 44 are read out and notified to the application control unit 36. The application control unit 36 activates the notified application program, and at that time, passes specific data, displays only the data specified by the specific data in the application display area 42, and stores other data associated with the application. The data is restricted (suppressed) from being displayed in the application display area 42.

  As described above, the data search device 10 extracts a search keyword from the data identified and displayed by the cursor, and searches for data including the search keyword from the data stored in the data storage unit 22. Then, the specific data for specifying the data found by the search and the search keyword used at that time are stored in the search history storage unit 34 in association with each other, and the search keyword is later determined from the data identified and displayed by the cursor.
