Embodiment Construction

[0038] Exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present invention to facilitate understanding, and they should be regarded as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

[0039] ElasticSearch is a commonly used data search engine, which is fast and easy to implement. However, this search engine only applies the frequency of text keywords as the only basis for searching. Words with a small frequency of text keywords are considered more important, while words with a high frequency of text keywords are considered less important, and the accuracy...

Abstract

The invention discloses a data search method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the following steps: extracting at least one target keyword from a search text, and respectively calculating a matching rate between the at least one target keyword and a plurality of set reference fields; comparing the matching rate with a set first threshold value, and under the condition that the matching rate is smaller than the first threshold value, calculating weights corresponding to the multiple reference fields by an analytic hierarchy process; and correcting the matching rate according to the weight so as to sort the plurality of reference fields according to the corrected matching rate to obtain a search result. The weight corresponding to the reference field is calculated by using the hierarchical word segmentation method, and the matching rate is corrected by using the weight, so that the search result is determined based on the corrected matching rate, and the accuracy of the search result is improved.

Description

technical field [0001] The invention relates to the computer field, in particular to a data search method and device. Background technique [0002] Data search is a very core function in the information field, and the information needed by users can be quickly located through search. In the prior art, the search sorting algorithm applied by the system is generally implemented by using ElasticSearch, an enterprise-level search engine. Among them, ElasticSearch is a distributed, highly scalable, high real-time search and data analysis engine, developed using Java language, which can easily enable large amounts of data to have the ability to search, analyze and explore. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] ElasticSearch uses the frequency of text keywords as the only basis for searching, and the accuracy of search results is low. Contents of the invention [0...
