The condition 1 column 430, the condition 2 column 450, and the condition 3 column 470 are search conditions between the above keywords (second character strings). Here, when the range covered by “and” is unclear, the range can be clarified using other symbols or the like.
The search query generation unit 108 described later generates a search query in the child mode with reference to the search category classification table 400.

  The search category classification table 400 includes a keyword (second character string) for guiding a search result when a first character string input by a user is searched as a search query to a predetermined category (search purpose or direction of search). ) And search conditions.

  Further, the search category and keywords in the search category classification table 400 may be added / changed / deleted. Thereby, it is possible to set the search category and guide the search result according to the age of the user. This also enables more accurate guidance to a healthy website.

  Here, when a search category or keyword in the search category classification table 400 is added / changed / deleted, a password input may be requested. Thereby, it is possible to prevent the user from adding / changing / deleting the contents of the search category and keywords without permission. For example, it is possible to configure such that a search category and a keyword cannot be added / changed / deleted without permission from the child who is a user without the approval of the input of the parent password as the administrator.

  The profile information storage unit 122 stores profile information including user age information. The age information stored in the profile information storage unit 122 is referred to when a mode setting unit 105 described later is set to an automatic setting state.

The mode setting unit 105 can set the mode in the mobile phone 1 to the child mode as the first mode or the adult mode (normal mode) as the second mode.
The mode setting unit 105 only needs to be able to set the child mode or the adult mode, and does not require a procedure for selecting one of the two modes. For example, the mode setting unit 105 may have means for switching to the other mode in a state where one mode is set. In the present embodiment, the initial setting is the adult mode (normal mode), and the mode setting unit 105 provides means for switching to the child mode.

  The mode setting unit 105 can be in an automatic setting state. In the automatic setting state, the mode setting unit 105 can automatically set (switch) the mode based on the age information stored in the profile information storage unit 122.

  When the mode setting unit 105 is in the manual setting state, it may be necessary to input a predetermined password in order to switch the mode. In addition, assuming that the mode setting unit 105 is in an automatic setting state, it may be necessary to input a predetermined password in order to change the profile information. Thereby, the mode change contrary to an administrator (mode setting person) can be suppressed.

  The mode determination unit 106 determines whether the mode set by the mode setting unit 105 is a child mode. When the mode determination unit 106 determines that the child mode is set, the predetermined function is restricted, and the content in which the second character string is added to the first character string input by the operation unit 101 is searched. The query is transmitted to the search server P (see FIG. 1).

  The search category selection unit 107 is configured to be able to select a predetermined search category from a plurality of search categories. The search category defines, for example, the search purpose and the direction of the search result. As the search category, for example, as shown in FIG. 5, learning, tour, experiential learning, book, school, history, and person can be exemplified. Also, as shown in FIG. 5, a plurality of keywords (second character strings) are associated with each of the plurality of search categories.

  Here, when the mode determination unit 106 determines that the child mode is set, the second character string added to the first character string input by the operation unit 101 corresponds to the selected search category. It is a keyword to do. For example, when the search category “learning” shown in FIG. 5 is selected by the search category selection unit 107, the first character string includes second character strings such as keywords “learning” and “study” associated with “learning”. Is added.

  Further, the search category selection unit 107 is configured to be able to select a plurality of search categories (see FIG. 6). In this case, a keyword associated with each search category is added to the first character string.

  In addition, the search category selection unit 107 can be configured so that the search category can be selected only in the child mode. Specifically, in the child mode, the search category selection box 402 shown in FIG. 6 can be displayed. In other words, in the adult mode (normal mode), the search category selection unit 107 can be configured not to select a search category. That is, in the adult mode (normal mode), the search category selection box 402 shown in FIG. 6 can be configured not to be displayed.

  Further, when no search category is selected by the search category selection unit 107, a search request by the search request unit 109, which will be described later, cannot be made. Here, when the child mode is set, a predetermined search category may be selected by the search category selection unit 107 as an initial setting.

  The search query generation unit 108 generates a search query to be transmitted to the search server (see FIG. 1) via the wireless communication unit 200. Specifically, when the mode determination unit 106 determines that the child mode is selected, the search query generation unit 108 stores the first character string input by the operation unit 101 in the second character string storage unit 121. A search query having contents to which a plurality of second character strings are added is generated. When the mode determination unit 106 determines that the adult mode (normal mode) is set, the search query generation unit 108 generates a search query including the first character string input by the operation unit 101 as a content.

  In the child mode, for example, when “learning” is selected as the search category, the search query generating unit 108 adds the content “and (learning or studying or...)” To the first character string. To generate a search query. Further, in the child mode, for example, when “person” is selected as the search category, the search query generation unit 108 selects “and (person or (person and person)...)” For the first character string. A search query is generated with the content added.

  Further, as shown in FIG. 6, when the search category selection unit 107 selects three search categories of “learning”, “book”, and “history”, the search query generation unit 108 uses the first character string in the child mode. A search query with a content of and ((learning or studying or ...) or (book or textbook or picture book or ...) or (history or founder or ...)) is generated.

  The search request unit 109 causes the wireless communication unit 200 to transmit (output) a search request including the search query generated by the search query generation unit 108 to the search server P. The search request unit 109 determines whether or not to make a search request to the search server P according to the mode determined by the mode determination unit 106 when no search category is selected by the search category selection unit 107. decide. Specifically, if any search category is not selected by the search category selection unit 107, the search request unit 109 searches the wireless communication unit 200 when the mode determination unit 106 determines that the child mode is selected. If the mode determination unit 106 determines that the adult mode (normal mode) is determined without outputting the search request to the server P, the wireless communication unit 200 outputs the search request to the search server P.

The display unit 21 is configured to be able to display a search screen, a search result from the search server P, and a Web page provided from the information providing server Q.
For example, as shown in FIG. 6, the display unit 21 is configured to be able to display a search screen on which an input box 401 and a search category selection box 402 are displayed. The input box 401 displays the first character string input by the operation unit 101. The search category selection box 402 displays a check box 405 and the name of the search category. The name of the search category displayed in the search category selection box 402 is the same as the name described in the search category name column 410 in FIG.

The operation unit 101 is configured to be able to input a first character string constituting a search query. The operation unit 101 is configured to be able to select a search category.
The user can input the first character string using the operation unit 101 while looking at the input box 401 (see FIG. 6) on the display unit 21.
Further, the user can select a search category by the operation unit 101 while looking at the search category selection box 402 (see FIG. 6) on the display unit 21.

Next, the operation of the mobile phone 1 will be described with reference to FIG.
FIG. 7 is a flowchart for explaining the operation of the mobile phone 1.
As shown in FIG. 7, first, the user displays a search screen on the display unit 21 by a predetermined operation in the operation unit 101 (ST1).
When the search screen is displayed on the display unit 21, the mode determination unit 106 determines the mode set by the mode setting unit 105 (ST2).
When the mode determination unit 106 determines that the child mode is set (ST3, YES), the display unit 21 displays a search screen including the input box 401 and the search category selection box 402 shown in FIG. The

  The user places a cursor (not shown) in the input box 401 so that characters can be input, and inputs the first character string constituting the search query while looking at the input box (ST4).

  Subsequently, the user aligns a cursor (not shown) with a predetermined check box 405 in the search category selection box 402 and checks the check box by a predetermined operation by the operation unit 101 (marks a predetermined mark). A category is selected (ST5).

  Subsequently, in order to request a search, the user performs a predetermined operation (an operation for confirming selection) with the operation unit 101 by placing a cursor (not shown) on the search button unit 403 (ST6).

  As a result, the search query generation unit 108 generates a search query having a content in which the second character string stored in the second character string storage unit 121 is added to the first character string input by the operation unit 101 (ST7). .

  Then, the search request unit 109 transmits the search query generated by the search query generation unit 108 to the search server P and requests a search using the transmitted search query (ST11).

  The search server P performs a search based on the search query and transmits search result information to the mobile phone 1. The mobile phone 1 receives the search result information via the communication unit 200 (ST12). Here, the second character string is added to the search query transmitted to the search server P, and the received search result has contents guided to a predetermined search category. That is, the search result is guided to the search category, and has a content with a small number of harmful Web pages (sites).

The user displays the search result on the display unit 21 (ST13).
In addition, the user requests predetermined Web page information from the information providing server Q via the communication unit 200 based on the search result. The information providing server Q transmits the requested web page information to the mobile phone 1. The mobile phone 1 receives (acquires) Web page information via the communication unit 200 (ST14).
Then, the user displays the predetermined web page acquired on the display unit 21 (ST15).

  When the mode determination unit 106 determines that the adult mode (normal mode) is set (ST3, NO), the display unit 21 displays a search screen that includes the input box 401 and does not include the search category selection box 402. The

  The user places a cursor (not shown) in the input box 401 so that characters can be input, and inputs the first character string constituting the search query while looking at the input box (ST8).

  Subsequently, in order to request a search, the user performs a predetermined operation (operation for confirming selection) with the operation unit 101 by placing a cursor (not shown) on the search button unit 403 (ST9).

  Thereby, the search query generation unit 108 generates a search query for the content of the first character string input by the operation unit 101 (ST10). That is, when the mode determination unit 106 determines that the adult mode (normal mode) is set, the search query is the content input by the user.

  According to the present embodiment, the search server P is requested to search for the content obtained by adding the predetermined second character string to the input first character string as a search query. It is possible to provide a mobile phone 1 that can avoid access to harmful websites without being hindered.

  Further, according to the present embodiment, instead of performing a search using a search query excluding a predetermined keyword in a plurality of keywords (first character string) input by a user, a predetermined keyword (second character string) is used. A search is performed with the search query of the added content. Thereby, while being able to obtain the search result according to a user's intention, the search result with few number of the harmful sites contained can be obtained.

  Moreover, according to this embodiment, since it has the keyword (2nd character string) corresponding to every predetermined | prescribed search category (search purpose), a search result can be guide | induced accurately.

  In addition, according to the present embodiment, in the child mode, the search request is not transmitted to the search server P when a predetermined search category is not selected. Thereby, it can suppress that the search for adult modes (normal mode) is made in child mode.
