Retrieval system and method for implementing data fast indexing

Abstract

The invention discloses a retrieval system for accomplishing data rapid search and a method thereof; wherein, the system comprises: a retrieval document establishing unit, a retrieval document storing unit and a retrieval serving unit; wherein; after forming a main document storage based on initial data source and increased data source, the retrieval document establishing unit establishes more than one retrieval documents with different levels by using different attributes of data in main document according to specific retrieval service requirement, and stores the retrieval documents in the corresponding retrieval documents document storing unit, and supplies the retrieval documents to the retrieval serving unit for the retrieval documents. The system and method of the invention accomplish rapid retrieval of increased data source with high retrieval efficiency and retrieval precision, so as to greatly enhance user experiencing in retrieval service.

Description

technical field [0001] The invention relates to retrieval technology, in particular to a retrieval system and method for realizing fast indexing of data. Background technique [0002] With the development of Internet technology, users generally use search engines for data retrieval services. Here, the so-called search engine is an online network tool that provides users with data retrieval. The first condition for retrieval services based on search engines is to create a data index based on the original data source, process the newly added data sources in sequence, and then generate a full inverted index to provide retrieval services. Here, the sequence processing can be understood as a process of processing a new data source and storing the processed data as a master document. The index document based on the main document is formed by the inverted index. And only after all the index documents are created can they be provided to users for retrieval services. [0003] To ...

AI Technical Summary

Problems solved by technology

[0003] To sum up, since the existing technology can only provide users with retrieval services after all index documents are created, and the existing technology is still used when there are a large number of new data sources, the time consumption of creating index documents will be relatively large. long

Therefore, with the existing technology, it is bound to be unable to create index documents based on the newly added data sources in a timely manner and provide them to users for retrieval services

Therefore, it cannot meet the needs of users for instant and fast retrieval.

Moreover, in the search service, the user has the problems of low search efficiency and low search accuracy, which reduces the user experience.

At present, there is no effective solution to the above-mentioned problems of meeting the needs of users for instant and fast retrieval, as well as low retrieval efficiency and low retrieval accuracy.
