Abstract

The embodiment of the invention provides an index structure and a retrieval method, device and equipment for unstructured data, and aims to construct the index structure for the unstructured data of aspecific business scene. The index structure comprises one of the following elements: index information generated by the system, user-defined service information of an application party and operatortrack information; classifying the unstructured data of the specific business scene based on the index structure; and according to the input keyword information, performing retrieval in the classifiedunstructured data of the specific business scene. According to the method, the retrieval performance of the unstructured data can be improved.

Description

technical field [0001] Exemplary embodiments of the present invention relate to the technical field of data processing, and in particular to an index structure and a retrieval method, device and device for unstructured data. Background technique [0002] With the increasing variety of business types and the continuous development of business, the granularity of business search and screening is getting finer and more, and the statistical dimensions are also increasing. Various sorting requirements, search time limit requirements, etc., the existing search methods are subject to relatively large limitations. [0003] In view of the wide variety of businesses now, and the index types of different businesses are not the same, the index fields added by using dynamic indexes will be disorganized, and front-line developers do not have a comprehensive understanding of unstructured data to a certain extent. The specified index type is not comprehensive, and it is not easy to manage....
