Search engine index construction method and device, medium and electronic equipment

Abstract

The invention discloses a search engine index construction method and device, a storage medium and electronic equipment. The method comprises the steps that first-version medical data and second-version medical data are acquired; the first version of medical data comprises multiple pieces of first user data, and the second version of medical data comprises multiple pieces of second user data; recovering a search engine index database corresponding to the first version of medical data through the snapshoot, and determining differential data at the same time; when the total number of the differential data is smaller than a preset threshold value, determining whether a search engine index corresponding to a user to which the differential data belongs exists in the search engine index database or not after the search engine index database is recovered; if yes, deleting the first user data of the user from the search engine index corresponding to the user, and writing the difference data of the user into the search engine index corresponding to the user; and if not, generating a new search engine index, and writing the difference data of the user into the new search engine index. The construction method disclosed by the invention has the effects of high speed and short time.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a method, device, medium and electronic equipment for constructing a search engine index. Background technique [0002] With the development of electronic information technology, big data also develops rapidly, playing an increasingly important role in people's lives. Medical big data is of great significance for precision medicine, disease risk control, and early warning. Medical data search can quickly locate patients and medical record data, helping doctors and patients quickly obtain the data they need. [0003] In the prior art, by exporting all the medical data from the medical database, after the search service preprocessing, use the database building script on the spark platform (a fast search engine designed for big data) to send it to the search engine to generate the search engine index, Medical data search can be realized based on search engine index.

AI Technical Summary

Problems solved by technology

[0004] It takes a very long time to build a search engine index using existing technical solutions, because a patient visit to a hospital may generate a large amount of medical data (such as a large number of inspection records, consultation records, medication records, etc.), it can be seen that the full amount of medical data is very large

Due to the limited number of concurrent database writing tasks that the search engine itself can bear, it takes too long to build the search engine index when a large amount of medical data is imported. In addition, when the search engine index is updated, the update amount is also too large, which causes the load of the search engine to increase. Affect online search requests
