Universal full-text search method

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 are a large number of structured data (referring to the data types stored in relational databases that can be expressed in two-dimensional table structure) and unstructured data (or electronic Files, compared with structured data, data types that are not convenient to express in a two-dimensional table structure are called unstructured data, which can include office documents in various mainstream formats, pictures, XML, HTML, various reports, images and audio). 70% of the data is unstructured data, and 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 : Centrally store the contracts, human resources, and official documents of the collaborative office s...

AI Technical Summary

Problems solved by technology

The result set filtering method has better performance in keyword retrieval, but it is easily affected by factors such as authorization ratio

The search condition expansion method has better performance in full-text search, but there will be a vacuum period of access control in the process of rebuilding the index
