Problems solved by technology
However, for some units and departments related to national security, such as scientific research departments, if search engines are used to search in the wide-area database, the scientific research direction and progress of the unit and department can be reversely deduced through the search information of internal personnel, resulting in confidentiality. Information leakage, in order to avoid this situation, these units with confidentiality needs tend to search within the scope of the local area network, but with the rapid advancement of technology, the search results provided by the local area network are not comprehensive and cannot meet the needs of users

The invention relates to the technical field of retrieval, in particular to an information retrieval method and device and a computer device. The information retrieval method comprises the steps of obtaining first retrieval information input by a user, and carrying out encryption operation on the first retrieval information and confusion information to obtain second retrieval information; callinga third-party search engine to retrieve the second retrieval information to obtain a second retrieval result, and caching the second retrieval result into a local database; and performing secondary retrieval in a second retrieval result of the local database according to the first retrieval information to obtain a first retrieval result corresponding to the first retrieval information. Accordingto the scheme provided by the invention, the safety of the information retrieval can be improved, and the problem of information leakage caused by calling an external retrieval engine is avoided.
Description
technical field [0001] The present application relates to the technical field of retrieval, and in particular, the present application relates to an information retrieval method, device, storage medium and computer equipment. Background technique [0002] When a user searches for data using a search engine, he enters a search keyword in the search box of the search engine, and the search engine searches the database for search results containing as many keywords as possible, and the user selects the target search result in the search results. Can. However, for some units and departments related to national security, such as scientific research departments, if search engines are used to search in the wide-area database, the scientific research direction and progress of the unit and department can be reversely deduced through the search information of internal personnel, resulting in confidentiality. In order to avoid information leakage, these units with confidentiality need...
