Abstract

The embodiment of the invention provides a data query method and device and belongs to the technical field of computer information retrieval. The method comprises the steps that an abbreviation whichis input by a user and needs to be queried is received, wherein the abbreviation contains at least two Chinese characters; Chinese character splitting is performed on the abbreviation to obtain multiple independent Chinese characters, and a pre-stored Chinese character table is queried to obtain a Chinese character identification number corresponding to each Chinese character; query is performed in a pre-stored database according to the Chinese character identification numbers corresponding to the independent Chinese characters, and full names, containing at least two independent Chinese characters in the abbreviation, in the database are obtained; and the full names obtained through query are ordered to obtain a query result. Through the data query method and device, the full names containing at least two Chinese characters in the abbreviation can be effectively queried according to the input abbreviation, and the queried full names are ordered according to a preset priority order.

Description

technical field [0001] The invention relates to the technical field of computer information retrieval, in particular to a data query method and device. Background technique [0002] Information retrieval system has developed to the stage of network and intelligence. The object of information retrieval has expanded from relatively closed, stable and consistent information content managed centrally by independent databases to open, dynamic, faster-updating, widely distributed and loosely managed web content.
