Problems solved by technology

In this way, each additional custom attribute field in the document will cause the overall index to become larger
Especially when different documents use different custom attribute fields, the index will be overlaid and enlarged, resulting in a great waste of server memory resources

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. During retrieval, values of retrievable fields in an index are retrieved, and when values matched with query keywords carried in a retrieval instruction are searched for and it is judged that the values matched with the query keywords have user-defined attributes, a user-defined field is obtained and analyzed to obtain user-defined attributesof the values matched with the query keywords; the user-defined field is a newly-built user-defined field in the index of a search engine, all specific values in the retrievable fields of documents and user-defined attributes corresponding to the specific values are stored in the user-defined field in a specific coded mode, and during retrieval, the user-defined field cannot be retrieved. By utilizing the same user-defined field for storing the user-defined attributes of all the specific values in the retrievable fields of different documents, and dynamically obtaining the user-defined attributes from the user-defined field during retrieval, the space occupied by the index is reduced, and the memory resource of a server is greatly saved.

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...
