The invention relates to the technical field of big data search, and discloses a data updating method and device for a retrieval database and a storage medium. The retrieval database comprises a base quantity database and an increment database; the method comprises the steps of: storing a base quantity library intermediate file and an increment library intermediate file which are respectively generated by the base quantity database and the increment database in the index establishment process; and combining the data of the incremental database to a base database, matching the intermediate file of the incremental database with the intermediate file of the base database, and balancing the index data of the base database. According to the data updating method for the retrieval database, a large amount of repeated calculation is avoided in the data merging process of the incremental database and the base database, the data merging time is shortened, and the risk is low.
Description
technical field [0001] The invention relates to the technical field of big data search, in particular to a data update method, device and storage medium for a search database. Background technique [0002] The retrieval database generally includes a full database and an incremental database. The basic database provides a data foundation for the basic index service, and the basic index service is used to query all documents up to a certain date; the incremental database is an incremental database. Quantitative indexing services provide the data foundation. Many search engines focus on time-sensitive searches. For example, for a popular event that just happened, the search engine needs to be able to search the page of the popular event in the first time. How to do this? Incremental indexing service can solve the time-sensitive search problem. [0003] The process of merging data between the existing incremental database and the basic database is as follows: [0004] a) When ...
