  Here, the index data storage unit 252 stores not only content purchased by the user of the terminal 20 but also index data of unpurchased content.

  Note that the storage unit 25 also stores the terminal ID of the terminal 20 and the like.

Hereinafter, the operation of the search system of this embodiment will be described.
(A) Index Data Generation Operation First, the operation when the server 10 generates index data will be described.

  In the server 10, the control unit 11 performs morphological analysis on the content data of each content stored in the content data DB 131 to generate index data.

  Then, the control unit 11 stores the index data of each content in the index data DB 132 in association with the content ID of the content.

  Here, the generation operation of the index data will be described with a specific example.

Here, it is assumed that the content data includes, for example, a sentence “we walked in the park because the weather is good today”, and an example of index data related to this sentence will be described.
(A-1) First Specific Example In this example, first of all, for the above sentence, “Today / Has / Weather / Good / So Good / So /, / Park / Dog / Walked //.” Morphological analysis. I do.

  Next, “today”, “weather”, “park” and “walk” which are nouns or verbs are extracted from the morphological analysis result.

Thereafter, position information is added to each of the extracted words, and “1: Today”, “2: Weather”, “3: Park”, and “4: Walk” are stored in the index data DB 132.
(A-2) Second Specific Example In this example, first, as in the first specific example, for the above sentence, “today / has / weather / good / so / so // park / in / Perform a morphological analysis, "Walk / Done /."

  Next, from today's morphological analysis results, not only nouns and verbs, but also particles, etc., "today" "ha" "weather" "ga" "good" "so" "," "park" "de" "walk" “Do” and “.” Are extracted.

After that, position information is added to each of the extracted words, and “1: Today”, “2: Ha”, “3: Weather”, “4: Ga”, “5: Good”, “6: So”, “7 :,” “8: Park”, “9: De”, “10: Walk”, “11: Done”, “11:.” Are stored in the index data DB 132.
(A-3) Third Specific Example In this example, first, as in the first and second specific examples, for the above sentence, “Today / ha / weather / good / so / so // park / De / Walk / Done. ”And conduct morphological analysis.

  Next, from the morphological analysis result, “today”, “weather”, “because it is good”, “in the park”, “walked” are extracted as one word including a plurality of parts of speech.

Then, position information is added to each of the extracted words, and “1: Today is”, “2: The weather is good”, “3: Good,” “4: In the park”, “5: Walked”, and the index. It is stored in the data DB 132.
(B) Index Data Download Operation Next, the operation when the terminal 20 downloads index data from the server 10 will be described.

  Here, the index data of the purchased content is downloaded from the server 10 together with the content data of the content when the content is purchased (details will be described later).

  Therefore, here, an operation when downloading index data of unpurchased contents will be described.

  First, in the terminal 20, the control unit 21 uses the transmission / reception unit 22 to the server 10 via the network when the terminal 20 is activated, when the search screen is activated, or periodically. The transmission request for the index data including the terminal ID of the terminal 20 is transmitted.

  In the server 10, when the transmission / reception unit 12 receives a transmission request for index data, the control unit 11 uses the terminal ID included in the transmission request as a key, and the user of the terminal 20 has already been purchased from the user DB 133. The content ID other than the content ID of the content (that is, the content ID of the unpurchased content) is extracted, the index data of the extracted content ID is read from the index data DB 132, and the terminal is transmitted via the network using the transmission / reception unit 12. 20 is added with a content ID and transmitted.

  In the terminal 20, when the index data is received by the transmission / reception unit 22, the control unit 21 stores the index data in the index data storage unit 252 in association with the content ID.

  At this time, if the unpurchased content is a book, only the difference index data may be additionally downloaded each time a new publication is issued, or all index data may be downloaded each time.

As a result, the index data storage unit 25 of the terminal 20 stores the index data at the time of the last download for each content.
(C) Content Search Operation Next, an operation when the terminal 20 searches for content will be described with reference to FIG.

  First, in the terminal 20, the control unit 21 displays a search screen on the display unit 23.

  Here, on the search screen, when a keyword is input to the keyword input field by the input unit 24 and the search start button is selected, the control unit 21 selects a content ID in which the index data hits the input keyword as an index. A search is performed from the data storage unit 252 (step A1). At this time, when the keyword included in the index data includes a plurality of parts of speech as described in the third specific example, the keyword that is input is not searched for the same keyword as the input keyword. Search for keywords that contain.

  Next, the control unit 21 extracts the content ID of the purchased content stored in the content data storage unit 251 (step A2).

  Next, the control unit 21 compares the content ID retrieved above with the content ID extracted above, classifies the content ID into a purchased content and an unpurchased content, and determines the content ID retrieved above. A list of contents is displayed on the display unit 23 by distinguishing between purchased contents and unpurchased contents (step A3).

  For example, the control unit 21 attaches a purchase / unpurchased icon to each content, or separates a screen that displays a list of purchased content and a screen that displays a list of unpurchased content.

  At this time, the control unit 21 may display a peripheral sentence of the keyword. For example, in the first to third specific examples, when the input keyword is “weather”, “the weather is good today” can be displayed as a peripheral sentence of the keyword.

  For example, in the case of purchased content, the control unit 21 reads a keyword peripheral sentence from the content data storage unit 251.

  On the other hand, in the case of unpurchased content, if the keyword included in the index data is only a verb or noun in the content data as described in the first specific example, the control unit 21 sets the transmission / reception unit 22. Using this, a transmission request for a peripheral sentence including the content ID and keyword position information is transmitted to the server 10 via the network, and the peripheral sentence is received as a response thereto. Further, as described in the second and third specific examples, if the keyword included in the index data represents all the content data, a predetermined number of keywords before and after the keyword hit in the search are indexed. Extracted from the data storage unit 252 to construct a peripheral sentence. For example, in the second specific example, when the input keyword is “weather”, the position information of “weather” is 3, and therefore, the index data storage unit 252 determines the previous and next keywords (for example, predetermined). If the number obtained is 2, the position information is extracted as keywords of 1, 2, 4 and 5), and a peripheral sentence “The weather is good today” is formed. Thus, in the case of the second and third specific examples, it is possible to display an unpurchased peripheral sentence without connecting to the network.

  Here, when the purchased content is selected from the list displayed on the display unit 23 by the input unit 24 (YES in step A4, YES in step A5), the control unit 21 selects the content of the selected content. The peripheral sentence of the keyword of the ID content data is read from the content data storage unit 251 and displayed on the display unit 23 (step A6).

  On the other hand, when an unpurchased content is selected (YES in step A4, NO in step A5), the control unit 21 uses the transmission / reception unit 22 to transmit the terminal ID and the terminal ID of the terminal 20 to the server 10 via the network. A transmission request for a content purchase screen including the content ID of the selected content is transmitted (step A7).

  In the server 10, when the transmission request for the content purchase screen is received by the transmission / reception unit 12, the control unit 11 uses the transmission / reception unit 12 to send a content purchase screen (content overview or Send purchase button).

  In the terminal 20, when the content purchase screen is received by the transmission / reception unit 22, the control unit 21 displays the content purchase screen on the display unit 23 (step A8).

  Here, when a purchase button is selected by the input unit 24 on the content purchase screen, the control unit 21 uses the transmission / reception unit 22 to transmit the terminal ID and content of the terminal 20 to the server 10 via the network. A content purchase request including the content ID is transmitted.

  In the server 10, when the content purchase request is received by the transmission / reception unit 12, the control unit 11 performs a content payment process, and the content data and index data associated with the content ID of the content are respectively stored in the content data DB 131. The content ID is read from the index data DB 132, and the content ID is added and transmitted to the terminal 20 via the network using the transmission / reception unit 12.

  In the terminal 20, when the content data and the index data are received by the transmission / reception unit 22, the control unit 21 associates the content data and the index data with the content ID, and the content data storage unit 251 and the index data storage unit 252 respectively. Remember me.

  In the present embodiment, it is assumed that the content data of the purchased content has been downloaded to the terminal 20. However, when a user uses a plurality of terminals 20, there is a case where a certain terminal 20 used by the user has content that the user has purchased at another terminal 20 but has not been downloaded.

  Therefore, in the terminal 20, when the content has been purchased and not downloaded, a screen for downloading the content data of the content may be displayed.

  In this case, in step A5 of FIG. 6, the control unit 21 determines that the selected content is not purchased, and uses the transmission / reception unit 22 to transmit the terminal ID and the terminal ID of the terminal 20 to the server 10 via the network. A transmission request for a content purchase screen including the content ID of the selected content is transmitted.

  In the server 10, when the transmission / reception unit 12 receives a transmission request for the content purchase screen, the control unit 11 searches the user DB 133 using the terminal ID and content ID included in the transmission request as keys, and the content. Has been purchased, and whether the content has been downloaded to the terminal 20 is determined.

  Then, if the content is not purchased, the control unit 11 transmits a content purchase screen to the terminal 20 via the network using the transmission / reception unit 12, and if the content has been purchased but not downloaded, the transmission / reception is performed. Using the unit 12, a screen for downloading content is transmitted to the terminal 20 via the network.

  As described above, in the present embodiment, the terminal 20 stores the content data of the purchased content purchased from the server 10 in the content data storage unit 251 in association with the content ID, and manages the content index managed by the server 10. Data is stored in the index data storage unit 252 in association with the content ID.

  Then, upon receiving an instruction to start searching for the content specifying the keyword, the content ID for which the index data hits the keyword is searched from the index data storage unit 252 and the content ID of the purchased content from the content data storage unit 251 is retrieved. A list of contents with the extracted content ID is extracted and displayed separately for purchased contents and unpurchased contents.

  Therefore, the user of the terminal 20 can search not only purchased content but also unpurchased content, and can easily determine whether the searched content is purchased or not purchased. .

  In the present embodiment, the terminal 20 displays the content data of the selected content when the purchased content on the list is selected, and selects when the unpurchased content on the list is selected. The purchase request screen for the selected content is displayed.

  Therefore, the user of the terminal 20 can easily purchase the content even if the searched content is unpurchased content.

  In the present embodiment, the terminal 20 has been described as searching for content. However, the present invention is not limited to this, and when the terminal 20 can be connected to the server 10 via a network, a content search request is made. May be transmitted to the server 10, and the server 10 may search for the content.

  In this case, the control unit 11 of the server 10 searches the index data DB 132 for the content ID of the index data that hits the keyword in response to the search request (including the keyword, user ID, and terminal ID) from the terminal 20 (step A1). ') Extract and compare the purchased content ID associated with the user ID of the user DB 133 (if necessary, the content ID downloaded to the terminal ID that requested the search) (step A2') A search result screen in which the content list is divided into purchased content and unpurchased content is generated and transmitted to the terminal 20 using the transmission / reception unit 12.

  And the control part 21 of the terminal 20 displays the search result screen received by the transmission / reception part 22 on the display part 23 (step A3 ').

  The present invention may be applied to a program for causing a computer to function as the server 10 and the terminal 20. It is also possible to store the program in a storage medium.
