Embodiment Construction

[0037] Such as figure 1 As shown, the system of the present invention includes an electronic file management platform, content extractor, content library, index creation device, index library, search engine, search condition construction device, authentication module, result set filtering device, and authorization security device, All business systems integrate their electronic documents and store them in the electronic document management platform. Business systems (such as collaborative office, ERP, etc.) no longer continue to store electronic documents; the electronic document management platform provides external search services, which are not only For users of business systems, the electronic file management platform also develops search services for direct users (that is, data can be directly searched through the search interface provided by the electronic file management platform). Because electronic files are managed centrally, data needs to be classified and managed. Fo...

Abstract

The invention provides a universal full-text search method which comprises a data preparation stage, an index creation stage, and a data search stage, wherein in the data preparation stage, a plurality of classification information data tables are created with a business system as a classification condition, and a relevance description field is set for every two of the classification information data tables; in the index creation stage, when the business system submits an electronic file to an electronic file management platform, an index creation device of the electronic file management platform is triggered, the content of the electronic file is started to be extracted, a metadata index database and a content index database of the electronic file are created respectively, a relevance relation of the metadata index database and the content index database are created, and access authorization control is conducted through the metadata index database; and in the data search stage, classification retrieval is subjected authorization control and user identification through the classification information data table and the relevance description field. Therefore, the search access limit can be flexibly set in one same system, the requirements of various kinds of authorization access control are met, and a user can access a file that does not need authorization.

Description

【Technical Field】 [0001] The invention relates to a full-text search method. 【Background technique】 [0002] With the gradual deepening and development of enterprise information construction, there is a large amount of structured data (referring to the type of data that can be expressed in a two-dimensional table structure stored in a relational database) and unstructured data (or electronic File, compared with structured data, the data type that is inconvenient to express in a two-dimensional table structure is called unstructured data, which can include office documents, pictures, XML, HTML, various reports, and images in various mainstream formats. And audio). 70% of the data is unstructured data. Now more and more unstructured data in enterprises are stored in a centralized manner, that is, the electronic file data of each business system is stored on a platform, such as : ERP (EnterpriseResourcePlanning enterprise resource planning system) system contracts, human resources...
