Data storage method and device

Abstract

The invention provides a data storage method and device; the data storage method is applied to a server, and comprises the following steps: obtaining grabbed data, and building an index for the grabbed data; storing the grabbed data and the index into a buffer memory; determining whether a backup condition is satisfied, and if yes, storing the grabbed data and index from the buffer memory into a hard disk for backup. The method and device can realize endurance of correlation data for data retrieval basis, thus ensuring effective performance in a data retrieval process.

Description

technical field [0001] The invention relates to the technical field of data retrieval, in particular to a data storage method and device. Background technique [0002] In order to improve retrieval efficiency, the server usually establishes indexes for the data on which data retrieval is based, and organizes the indexes together to form an index library. Extract some information as an index. For example: for a document, the corresponding index is the text content extracted from the document or the attribute parameters of the document, and the attribute parameters of the document may be: author name, document category, and so on. [0003] In the prior art, in order to ensure the efficiency of data retrieval, the server usually builds an index for the captured data after obtaining the captured data, and then saves the captured data and the index in the cache for subsequent execution When data is retrieved, the retrieval is completed directly based on the data and indexes sto...

AI Technical Summary

Problems solved by technology

[0004] However, since the captured data and indexes are stored in the cache, this will cause the following problems: when the server is powered off or fails, the relevant data in the cache will disappear or there will be exceptions, which will undoubtedly affect the data retrieval process the effective conduct of
