Abstract

The invention discloses an information full-text retrieval method based on intra-domain information access permission, which comprises the following steps: extracting key field information of each unit data from updated data according to a preset information extraction rule, and adding the key field information into an index submission queue according to a preset format; obtaining identity authentication information of a login user; and screening unit data containing the search request content and a field for describing the access authority, the authority information of which is higher than the identity authentication information of the login user, based on a preset authority matching rule by utilizing the search request content of the login user and the identity authentication informationof the login user, and returning the unit data. The method is based on the Lucene search engine, the engine only returns data with right access during retrieval, secondary screening is not needed, and the risk of data leakage is reduced to the maximum extent. Meanwhile, the index is established through the keywords, the matching speed is high, the accuracy is high, high concurrency support of Lucene is quite good, and the search efficiency in the high concurrency environment is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of data retrieval, and more specifically, to a method and system for full-text retrieval of information based on information access authority within a domain. Background technique [0002] A full-text search consists of four parts: searcher, indexer, retriever and user interface. The function of the collector is to collect synchronization information in the domain. The function of the indexer is to understand the information searched by the searcher and extract the index items to generate the index table of the document library. The function of the retriever is to quickly retrieve documents in the index library according to the user's query, evaluate the relevance between the document and the query, sort the results to be output, and implement a user relevance feedback mechanism. The role of the user interface is to enter user queries, display query results, and provide user relevance feedback mech...
