Data searching method and device thereof

Abstract

The invention provides a data searching method and a device thereof. The data searching method comprises the following steps: obtaining the search key word input by a user, and searching a word index module according so as to key words to obtain the preset word identification information corresponding to the search key word in the word index module; searching an inverted index module according tothe word identification information so as to obtain the preset compressed and stored document information corresponding to the work identification information in the inverted index module; decompressing the document information so as to obtain the document identification information of the document corresponding to the search key word; searing a work position index module according to the search key word and the document identification information so as to obtain the position information of the search key word in the document corresponding to the document identification information; and displaying the document according to the document identification information and the position information. The data searching method and the device thereof can reduce the hardware resource consumption of the searching system and improve the searching efficiency.

Description

technical field [0001] The invention relates to a data processing method and device, in particular to a data retrieval method and device. Background technique [0002] Full-text search is a very common way to obtain the required information through the network. Full-text search generally uses indexing technology to achieve retrieval. Every time a query is made, it is necessary to find the corresponding document based on the retrieved keywords and perform a series of calculations based on the search expression. These operations will generate a certain amount of I / O consumption. And CPU consumption, and the resource consumption of a single query is directly related to the resource consumption of multiple queries. As the amount of network visits increases, this resource consumption will directly affect the load capacity of the network search system, that is, the smaller the resource consumption of a single query, the greater the load capacity of the network search system. Whe...
