Search engine query string generation method and device and search engine system

Abstract

The invention relates to a search engine query string generation method and device and a search engine system. The method includes generating a base query string according to a received user query request; on the basis of the base query string, generating a plurality of sub query requests according to public logic and interface logic of configuration files; connecting the sub query requests to generate a search engine query string. According to the technical scheme, the search engine query string can be generated dynamically, and modification and maintenance can be performed as required by modifying configuration parameters of the configuration files. The engine querying performance is improved, the engine maintaining cost is reduced, and external malicious operations on the search engine can be avoided.

Description

technical field [0001] This application relates to the field of data processing, in particular to a method and device for generating search engine query strings and a search engine system. Background technique [0002] With the rise of the search economy, people pay more and more attention to the performance, technology and daily traffic characteristics of major search engines around the world. Therefore, the bottleneck and performance improvement of search engines have gradually become the current research hotspots. [0003] In some search engines (such as vertical search engines), when a user submits a query to the search engine, the user submits query keywords (that is, natural language, such as MP3) to the search engine. The internal search engine only accepts or recognizes query strings in a specific format (ie, machine language), for example, q=[MP3]OR[MP3 recorder]AND[MP3 earphone]&filter:customer_id=54321&sorttype:+update_time&count= 12. Therefore, it is necessary ...

AI Technical Summary

Problems solved by technology

[0006] (1) In order to ensure that various business needs are met, the number of templates corresponding to business types is usually very large. When modification or maintenance is required, it is often impossible to respond quickly with changes in application requirements or changes in engine interfaces, which is not conducive to Maintenance and maintenance costs are also high

[0007] (2) Since the search engine query string is generated at the front end of the search engine, and the search engine query string is often lengthy and complex, the interaction between the front end and the back end of the search engine is complex and unfriendly

In addition, due to the use of templates to generate search engine query strings, the external interface has poor scalability

In addition, the engine exposes the internal query syntax to the outside world, making it easy for illegal or misoperated users to cause malicious or mistaken attacks on the engine
