Abstract

Embodiments of the invention provide a query method and device, and the method and device are applied to the technical field of internet. The method comprises the following steps of: obtaining a query parameter and judging whether the query parameter accords with a grammatical norm or not; when the query parameter accords with the grammatical norm, extracting a self-defined query language included in the query parameter; analyzing the self-defined query language and encapsulating the query parameter into a structured query language corresponding to a search server; and sending a query request to a cluster of the search server according to the structured query language so as to obtain a query result, aiming at the query parameter, returned by the cluster of the search server. Compared with the existing query method, the query method provided by the invention is capable of achieving the aim of carrying out query according to a self-defined query expression language, and the self-defined query expression language is concise in language and easy to learn, so that the development cost is reduced and the development efficiency is improved.

Description

technical field [0001] The present invention relates to the field of Internet technologies, and in particular, to a query method and device. Background technique [0002] With the rapid development of the Internet, the amount of network information data has grown exponentially. Internet users are increasingly searching for data, and the requirements for the accuracy of data captured from massive data are also getting higher and higher. Elasticsearch is a Lucence-based search server that provides a full-text engine with multi-user distributed search capabilities. [0003] However, the learning and maintenance costs required by Elasticsearh are relatively high, especially the RESTful query API (Application Programming Interface) with JSON (JavaScriptObject Notation) as the data format. The query syntax is complex and diverse. There is a certain difficulty for users of database SQL (Structured Query Language, Structured Query Language). Among them, JSON is a lightweight data...
