Install and configure Solr 7.2 in the latest version

Solr is an independent enterprise-level search application server that provides APIs similar to Web-service. You can submit an XML file of a certain format to the search engine server through an http request to generate an index. You can also submit a search request through the Http Get operation and obtain the returned results in XML format.

Solr is a high-performance full-text search server developed by Java 5 and based on Lucene. At the same time, it is expanded to provide a richer query language than Lucene, and at the same time, it is configurable and scalable, and the query performance is optimized, it also provides a complete functional management interface and is a very good full-text search engine.
