5 is a flowchart illustrating an operation procedure according to the embodiment. 4 to 8 and 11 show specific examples of each storage device.
9 and 10 show specific examples of the display screen. The search condition including the keyword and the data type supplied from the terminal is supplied to the search condition storage unit 11 (step SA1), the keyword is stored in the keyword storage unit 21 (step SA2), and the data type is determined by the data condition. It is stored in the storage unit 22 (step A3).

FIG. 4 shows an actor's name, which is a specific example of a two-word keyword, and a movie title, "John Wayne" and "John Wayne."
5 shows that "image" is designated as the type of data, which is stored in the keyword storage unit 21 and the data condition storage unit 22, respectively. This is a specific example.

As shown in FIG. 5, the data conditions stored in the data condition storage unit 22 are selected from the data conditions specified in the table 52. The data condition is selected from four types of data names corresponding to the identification numbers, and as shown in the search designation column 51, "image" of # 1 is specifically selected. The storage items stored in the data condition storage unit 22 include a search character string (file extension or tag) used for searching the data and an identification number # 1 for uniquely identifying the information in the data condition storage unit 22. ~
# 4 included.

The search character string is automatically determined according to the type of data. If the data is a file that is independent of the page, such as images and sounds, the extension is used for the search string, and the data is not independent of the page and becomes part of the file, as in the table , The tag is used for the search character string. The selection condition 51 is stored as an identification number of data specified by the user as a search condition.

The page search means 12 searches the Internet using the keywords in the keyword storage unit 21 as search conditions, and stores a list of URLs of the corresponding pages in the URL storage unit 23 (step A4). FIG. 6 shows a specific example of the storage contents of the search result obtained by searching for a movie-related page under the above conditions and storing it in the URL storage unit 23. "
Two pages are found, "hollywood" and "academy".

When the search for the page is completed, the first URL is obtained from the URL storage unit 23 (step A5), and the contents of the page are obtained from the Internet (step A6). Data matching the condition specified by the search condition 51 in the condition storage unit 22 is searched in each page (step A7).
In the search, as shown in FIG. 5, a file extension or tag corresponding to each data is used as a search character string.

When the corresponding data is searched (step A8), the search result creating means 14 operates to store a tag referring to each data and a tag referring to a page including the data in the search result storage unit 25. (Step A9). FIG. 7 is a specific example in which a search result when an image is searched for on a movie-related page is stored. The extension “.gif” is added, and “p
“icture1” and “picyure2” are found, and “photo1” and “photo2” are found for “academy.” Thus, the search results refer to the searched data and the searched pages. It consists of tags and is stored as HTML information.

In the following, the process of step A9 in FIG. 2, ie, "search result creation" will be described in accordance with the flowchart of FIG. First, it is checked whether the tag of the page has already been stored in the search result storage unit 25 (step B1), and if it has not been stored yet, it is stored (step B2). Next, it is checked whether the searched data is included in the HTML file of the page or in an independent file (step B3).

As described above, data such as images and sounds is a file independent of the page, but tabular data is generally a part of a file independent of the page. If the data is an independent file, a tag referring to the file is created (step B4). If the data is part of a page file, the data part is copied to a new file and stored in the temporary data storage unit 24 (step B5), and a tag for referring to the stored file is created (step B5). B6).

After that, the tag created in step B4 or B6 is stored in the search result storage unit 25. FIG.
Shows a specific example of the storage content of the temporary data storage unit 24. Unlike the case of the movie-related search described above, a table is searched as data. When the creation of the search result for one piece of data is completed, the process returns to step A7, and the next page that matches the condition of the data condition storage unit 22 is searched in the same page. Searching the above data and creating search results,
This is repeated until there is no more data that meets the conditions in the page (step A8).

Thereafter, the next URL is stored in the URL storage unit 23.
, And similarly, the last UE in the URL storage unit 23
The generation of the search result is repeated until the search result reaches L (steps A10 and A11). When the data search for all the searched pages and the creation of the search results are completed, the search result supply means 15 is activated and supplies the contents of the search result storage unit 25 to the terminal (step A12).

Next, the operation of the embodiment will be described using a specific example. As shown in the screen 91 in FIG. 9, the user searches for a picture of a movie called a stagecoach starring John Wayne, and the keywords “John Wayne” and “Stroller” are used as keywords.
Is specified, "image" is specified as the data type, and the Internet is searched using them as search conditions.

The search result at this time is as shown in a screen 92, and the keyword storage unit 21 at that time is as shown in FIG. 4, and the data condition storage unit 22 is as shown in FIG.
When the user executes a search, first, the Internet is searched using the two keywords in FIG. 4 as a condition, and the URL of the searched page is stored in the URL storage unit 23 as shown in FIG. Then, in the page indicated by each URL in FIG. 6, a search character string ".gi" corresponding to the image in FIG.
A file name including any one of f ”,“ .jpg ”,... is searched, and a reference tag corresponding to the file and a reference tag corresponding to the page are shown in FIG. Is stored in the search result storage unit 25 in HTML format.

Next, the information in the search result storage unit 25 is supplied and displayed on the user terminal, and as a result, a screen 92 is obtained. Here, if the user selects one of the tags on the screen 92, the corresponding data or page is displayed on the terminal. FIG. 10 shows an example in which table data is searched for in place of the image described above. Here, in order to obtain the price list of the personal computer, as shown on the screen 101, "PC" and "price" are specified as keywords and "table" is specified as the data type, and the screen 102 is obtained as a search result. .

At this time, the keyword condition storage unit 21
As shown in FIG. 1, the data condition storage unit 22
As a result of performing a search using these, a search result illustrated in FIG. 13 is obtained in the search result storage unit 25. Unlike the case of FIG. 9, the data search is not performed by the file extension but by the search condition 121 of FIG.
Tag <TAB in table 122 corresponding to (represents table)
LE ”is used as the search string. In this case,
Only part of the table data is copied to a separate file,
As shown in FIG. 8, the HTM is stored in the temporary data storage unit 24.
Saved as an L file.

Further, as shown in FIG. 13, the tag of the table data in the search result storage unit 25 is set so as to refer to the file stored as described above. As mentioned above,
ADVANTAGE OF THE INVENTION According to this invention, a user can search only the information which he really needs exactly, without being bothered by a large amount of search results.
