Embodiment Construction

[0056] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0057] The invention provides a query processing method, which can reduce retrieval time, improve query response speed, and thereby improve search engine performance.

[0058] On the premise of not affecting the retrieval effect, the present invention mainly shortens the retrieval time by reducing the number of documents (rank_size) retrieved by rough sorting, thereby improving the overall performance of the engine. The present invention re...

Abstract

Provided is a query processing method, comprising: filtering, from an original chain corresponding to a query term, documents numbering less than the number of documents in the original chain, so as to establish at least one supplementary chain corresponding to the query term (101); and on the basis of a current query service type and current query term, selecting at least one supplementary chain corresponding to the current query term, performing document retrieval and forming a retrieval result (102). Further provided are a query processing device and a processing apparatus. The present method can reduce retrieval time and improve query response speed, thereby improving search engine performance.

Description

technical field [0001] The present invention relates to the technical field of mobile Internet, in particular to a query processing method, device and equipment. Background technique [0002] At present, with the rapid development of Internet technology, the amount of network information is constantly increasing, and search engines can help users quickly find the information they need in massive amounts of data by building effective data indexes. However, as the user's demand for information retrieval becomes more and more vigorous, the performance requirements of the search engine are also getting higher and higher. [0003] The performance optimization of search engines can be considered from different aspects, such as adjusting the structure of the engine itself, optimizing the index structure, and so on. At present, most of the optimization of search engines starts from the engine itself to optimize the overall performance of the engine, which has little connection with...
