Abstract

The invention discloses a distributed type search result gathering and page turning method and system based on sampling. The distributed type search result gathering and page turning method and system can obviously solve the problem that network bandwidth and calculation consumption are large in a distributed type search result gathering and page turning process. Meanwhile, the distributed type search result gathering and page turning method and system can be improved to be applied to result gathering and page turning of other distributed type inquiring systems. The technical scheme is that index data are sliced to form index file slices to be distributed into shard-search servers to finish initializing index files, and search result gathering nodes receive gathering and page turning requests of an external system to carry out the specific steps of distributed search result gathering and page turning.

Description

technical field [0001] The invention belongs to the technical field of massive data processing, and in particular relates to a method and a system for the problem of merging and turning pages of distributed search results. Background technique [0002] The emergence of e-commerce platforms (B2B, B2C, etc.) has greatly facilitated people's lives. When people rely more and more on these platforms, they also put forward higher requirements on the platforms themselves: for example, transactions on Taobao, Jingdong, etc. On the platform, people hope to find the products they need more, faster and more accurately; for e-commerce companies, to meet these requirements of people, they usually need an efficient and accurate mass search at the technical level system. Due to the huge and rapid growth of retrieval data, traditional centralized search systems have become increasingly incapable of retrieval tasks on large e-commerce platforms. [0003] With the development of distributed...
