Abstract

PURPOSE:To provide a character string retrieving device which is superior in operability by providing a body direct display means which directly displays the body of an item completely matching a retrieval word. CONSTITUTION:When the index of the target item whose entry key completely matches the retrieval word is retrieved by using indexes which are made hierarchic, the block number of the data block containing the body data and the offset value in the block are obtained from a pointer for the body data stored after the entry key of the obtained index. Then the physical address of the body data of the target item is calculated from the obtained block number and offset value. Then the body data are read out of a CD according to the physical address and displayed in a display memory. Then the target item corresponding to the body data is displayed on a display screen.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention searches information stored in an information storage medium such as a compact disc (hereinafter abbreviated as CD) by a search word or the like composed of a character string of one or more characters, and displays the text of the searched item. The present invention relates to a character string search device displayed on a display device as a search result.

[0002]

2. Description of the Related Art In recent years, in order to improve workability in collecting information from documents such as English-Japanese dictionaries and kanji dictionaries, information storage media such as CD-ROMs, which can retrieve a large amount of information at high speed, have been developed. Various character string search devices have been developed that store the contents of documents as a document file, search the document file using a search word or the like consisting of a character string, and display the text of the searched item.

A general document file will be described below. FIG. 9 is a schematic diagram of a general document file. 1
Is a document file stored in an information storage medium such as a CD-ROM, 2 is a document management block for managing the entire document file 1, and 3 is the content of a document such as a dictionary (text / image) stored as the document file 1.・ Text data indicating voice etc.), 4 is various indexes for searching by a search word consisting of a character string input by the user, and 5 is for searching by selecting a menu according to predetermined classification contents Of the menu data, 6 is a viewpoint management block defining a plurality of search conditions, and 7 is an external character font for displaying a specific character used in the document stored as the document file 1 as an external character.

The conventional character string search device is unique according to the search order defined in any one of the various indexes 4, the menu data 5, and the viewpoint management block 6, the search word entered by the user, the selection, etc. The character data in the body data 3 of the item determined by is displayed as a sentence on the display device,
When other data such as image data and audio data are present in the body data 3, these are also reproduced.

With respect to the conventional character string retrieving apparatus configured as described above, a retrieval method using the retrieval word will be described below. 10 is a diagram showing a search menu selection screen of the conventional character string search device, FIG. 11 is a diagram showing a search word input screen of the conventional character string search device, and FIG. 12 is a diagram of the conventional character string search device. It is a figure which shows a corresponding item list screen, and FIG. 13 is a figure which shows the text display screen of the conventional character string search device.
In FIG. 10, 8 is a display screen on which characters such as the text are displayed, 9 is a prefix matching search menu for searching for items whose front part matches the search word entered by the user, and 10 is entered by the user. Succeeding match search menu for searching items whose search word and the rear part match, 11 is a condition search menu for performing a search according to a plurality of search conditions input by the user, and 12 is a predetermined classification content A menu search menu for performing a search by selecting a menu according to the following, 13 is a cursor for pointing a position on the display screen 8, 14 is a next page key for displaying a menu, an item, etc. of the next page, 15 Is a return key for returning to the previous screen, 16 is a menu at the position of the cursor 13,
This is a determination key for determining selection of items and the like. Figure 11
In FIG. 17, 17 is a search word consisting of a character string input by the user from the keyboard, 18 is a delete key for deleting the search word 17, 19a is a prefix match search for searching for an item whose prefix matches the search word 17 Is the key. In FIG. 13, reference numeral 20 is a re-key for returning to the search word input screen and performing a search again.

Here, as an example, the user selects the item "se".
A case of searching for "e" using the search word 17 will be described. First, as shown in FIG. 10, in the search menu selection screen, move the cursor 13 to the prefix match search menu 9 (or suffix match search menu 10) and press the enter key 16
Press. Next, as shown in FIG. 11, "SEE" is input as the search word 17 from the keyboard (not shown) on the search word input screen, and the prefix match search key 19a is pressed. As a result, the character string search device searches for an item whose front matches "SEE" which is the search word 17, and displays the result on the display screen 8 as a corresponding item list screen as shown in FIG. Here, when the user confirms that the cursor 13 is pointing to the item "see" in the corresponding item list and presses the decision key 16, the user selects the item "see" as shown in FIG. The text was displayed on the display screen 8.

As described above, even when the target item to be searched is completely unknown, a part of the front or rear of the target item is searched as the search word 17, and the item corresponding to the search word 17 is searched. The text of the target item was obtained by selecting the target item from the list.

[0008]

However, in the above-mentioned conventional configuration, since the forward / backward matching search is always performed when searching by the search word, the target item to be searched is accurately known. , Even if you enter this as a search term, a forward / backward matching search is performed, and not only the target item that exactly matches this search term, but also the item that partially matches this search term It is displayed as a list, select the desired item from this with the cursor,
There is a problem that the text of the target item cannot be displayed unless the enter key is pressed, which is cumbersome, time-consuming, and lacks in workability.

The present invention solves the above-mentioned problems of the prior art, in which the item to be searched is accurately known, and when this is input as a search word, the text of the target item can be displayed directly. It is an object of the present invention to provide a character string search device with excellent workability.

[0010]

In order to achieve this object, a character string retrieval apparatus of the present invention retrieves / displays information stored in an information storage medium such as a CD using a retrieval word composed of a character string. A character string search device that does not display a corresponding item list showing a list of the items corresponding to the search word when the item to be searched is accurately known and is input as the search word. It has a configuration including a body direct display means for directly displaying the body of the item that exactly matches the search word.

[0011]

With this configuration, the text direct display means for directly displaying the text of the item that completely matches the search word without displaying the corresponding item list showing the items corresponding to the search word is provided. The target item to be processed is accurately known, and when this is input as a search term, the text of the target item can be directly displayed.
