Problems solved by technology

[0003] Artificial intelligence is widely used in search engines. However, as the amount of information continues to grow, the amount of information that needs to be traversed by the search increases correspondingly, and the search time is correspondingly longer.
In this case, related technologies use complex search strategies, which will make the search time-consuming and affect the user's experience of using the search engine

Abstract

The invention provides a query optimization method and a query optimization device of a search engine, electronic equipment and a computer readable storage medium. The method comprises the following steps: obtaining a historical query record of a search engine, wherein the historical query record comprises a plurality of query statements, and generating a syntax tree based on words included in the query statements; based on the amount of information included in an inverted list corresponding to each word in the syntax tree, adjusting the execution sequence of the words in the syntax tree; searching based on the syntax tree after the execution sequence is adjusted, and determining the execution sequence of each word in the syntax tree according to a search result, wherein the execution sequence minimizes the overall search cost, and the syntax tree is used for searching when the search engine receives the query statements. Through the invention, search consumption can be reduced.

Description

technical field [0001] The present application relates to search technology, in particular to a search engine query optimization method, device, electronic equipment and computer-readable storage medium. Background technique [0002] Artificial Intelligence (AI) is a theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best results. [0003] Artificial intelligence is widely used in search engines. However, as the amount of information continues to grow, the amount of information that needs to be traversed by the search increases correspondingly, and the search time is correspondingly longer. In this case, related technologies use complex search strategies, which will make the search time-consuming longer and affect the user's experience of using the search engine. Contents of the...
