Abstract

PURPOSE:To improve the response of a document storing/retrieving system at storage of a document by generating a trigger for an index generating request in order to complete the storage processing and generating a document retrieving index in a delay type and an asynchronous type in a different route from the storage processing based on a trigger. CONSTITUTION:A key word group or a key word group ID group is added to a stored document 1, and the document control information and a document main body are stored in a document control information file 3 by a document store means 2. Then an index generation request of the corresponding document is stacked into a trigger information file 4. Thus the document is stored. An index generation means 5 works when the index generating request is stacked into the file 4. An index key word group ID information file 6 is searched based on a key word group ID and the trigger information of the file 4 for a key word group and a key word group ID group. The keyword group thus obtained and the document are added to the index and the index information is stored in an index information file 7. A document retrieving means 8 searches the file 7 based on a retrieving key word 9 and takes it out as a retrieved document 10.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document storage and retrieval system that stores documents and searches for documents using an index.

[Conventional technology]

Conventionally, in this type of document storage and retrieval system, the document storage means and the index generation means operated in series in synchronization, and there was no need for exchange of processing triggers between the means corresponding to the trigger information file.

[Problem to be solved by the invention]

In the conventional document storage and retrieval system described above, document storage and search index generation processing are synchronized, so the response time for storage includes the index generation processing time, resulting in improved responsiveness. There are some drawbacks.

[Means to solve the problem]

The document storage and retrieval system of the present invention provides a document management information file for storing document management information and a document body to which a keyword group identification ID group for identifying a keyword group for search or a keyword group set in advance is added. a trigger information file for stacking index generation requests; a document storage means for storing the document management information and the trigger information; an index generation means for generating an index of the document, and an index generation keyword group identification ID for extracting a series of keywords associated with the keyword group identification ID.
An information file, an index information file for storing index information, and a document search means for finding a corresponding document in the index information file at the time of a search request and retrieving the corresponding document from the document management information file. It is characterized by

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 shows the configuration of an embodiment of the present invention.

1 is a stored document, 2 is a document storage means, 3 is a document management information file, and 4 is a trigger information file. A keyword group or a keyword group identification ID group is added to the stored document 1, the document storage means 2 stores the document management information and the document body in the document management information file 3, and the index generation request for the document is sent to the trigger information file 4. The document storage process is completed.

5 is an index generation means; 6 is an index generation keyword group identification I;
The D information file 7 is an index information file, and when an index generation request is stacked in the trigger information file 4, the index generation means 5 operates.

Then, according to the trigger information in the trigger information file 4, when the keyword group and keyword group identification ID of the corresponding stored document are found, the keyword group identification ID is obtained by searching the index generation keyword group identification ID information file 6 using the keyword group identification ID. The keyword group and the stored document are indexed and the index information is stored in the index information file 7.

8 is a document search means, 9 is a search keyword, and 10 is a search document. The document search means 8 searches the index information file 7 based on the given search keyword 9 and extracts the corresponding document as the search document 10. .

FIG. 2 shows the expression format of the document management information and document body in the document management information file 3, including a document identifier a1 that uniquely identifies the document, and several keywords or keyword group identifiers specified when storing the document. It consists of IDa2, index reflection status a3 indicating whether the index of the document has been registered in the index information file, and document body a4.

FIG. 3 shows the expression format of the trigger information in the trigger information file 4, in which a document identifier b! that uniquely identifies a stored document is used. and an action b2 indicating an operation (registration, modification, deletion) on the document.

FIG. 4 shows the expression format of the index generation keyword group identification ID information in the index generation keyword group identification ID information file 6, in which the keyword group identification IDcl is created based on the keyword group identification ID added to the stored document 1. is searched,
The corresponding keyword c2 is extracted, and index information is created according to the extracted keyword C2.

FIG. 5 shows the expression format of the index information in the index information file 7, which is composed of a keyword dl serving as an index and a document identifier d2 that uniquely identifies the keyword dl and the indexed document.

〔Effect of the invention〕

As explained above, the present invention generates a trigger called an index generation request when storing a document, completes the storage process, and performs index generation process for document search based on the trigger in a route different from the storage route. By doing it asynchronously,
This has the effect of speeding up responsiveness when storing documents.

Further, since searching for the document immediately after storage does not actually occur, even if the index generation process is slightly delayed, no practical problem occurs.
