Solr-based unstructured file retrieval method and device, equipment and storage medium

Abstract

The invention provides an Solr-based unstructured file retrieval method and device, equipment and a storage medium. The method comprises the following steps: pre-utilizing a Solr search server to index unstructured files to be indexed in a database to generate an index information table, wherein the index information table comprises an index relationship between keywords and unstructured file numbers, and the keyword in the index relationship is located in the unstructured file corresponding to the unstructured file serial number in the index relationship; when a retrieval request initiated by a user is received, determining a retrieval keyword according to the retrieval request; based on an index relationship included in the index information table, determining an unstructured file number corresponding to the retrieval keyword; and returning a retrieval result according to the determined unstructured file number. According to the scheme, the retrieval efficiency of the unstructured file can be effectively improved while the method can adapt to larger data volume of the retrieved database.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of data retrieval, and in particular to a Solr-based unstructured file retrieval method, device, device, and storage medium. Background technique [0002] Due to the rapid advancement of informatization, the amount of product characteristic data is increasing exponentially. The vast majority of product characteristic data is unstructured data in a variety of formats, stored in the form of documents, pictures, videos, models, etc. Technically, unstructured data is more difficult to standardize and understand than structured data, so the storage, retrieval, release and utilization of unstructured data is the key to quickly retrieve the required information from the explosive growth of product characteristic data. Traditional relational databases can no longer adapt to the huge amount of data, and have encountered bottlenecks in terms of scalability and fault tolerance. At the same time, ...
