Embodiment Construction

[0068] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0069] In a document search engine, in order to quickly retrieve content, the information written in all fields of the document is processed to generate an index. When searching for data, you can directly search for the searchable fields of the index to quickly find documents that meet your requirements. The document to be written may contain any number of fields (also called columns), and the index generated for each document incl...

Abstract

The invention provides a data search method and device. Retrieve the values ​​of the retrievable fields in the index during retrieval, find the value that matches the query keyword carried in the search command, and obtain and parse the value when it is determined that the value that matches the query keyword has a custom attribute A custom field to obtain a custom attribute with a value matching the query keyword; wherein, the custom field is a newly created custom field in the index of the search engine, and the document can be stored in a specified encoding method in the custom field Retrieves all specific values ​​in the field and the custom properties corresponding to that specific value, and the custom field is not retrieved when doing the retrieval. By using the same custom field to store all the custom attributes of specific values ​​in the searchable fields of different documents, and dynamically obtain the custom attributes from the custom field when retrieving, the space occupied by the index is reduced, and the server is greatly saved. memory resources.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a data search method, a data search device, a computer storage medium and a computing device. Background technique [0002] ElasticSearch is an open source document search engine based on the Lucene framework. It has distributed multi-user capabilities and can quickly store, search and analyze massive data. It is currently a popular enterprise-level search engine. The design of ElasticSearch for cloud computing can achieve real-time search and high-performance computing. At present, the mature Elasticsearch5.x version is widely used in various full-text retrieval platforms and cloud computing service platforms, such as Elasticsearch5.2.0, Elasticsearch5.5.3, etc. [0003] An index is a data structure created in a search engine to quickly retrieve content. In ElasticSearch, the information written into all fields of the document is indexed, processed and written into the da...
