Faceted search has become a critical feature for enhancing findability and the user search experience for all types of search applications.

We talked about the basic usage and configuration file of SOLR several times before, and then we started our real code journey. 1) start with a simple program: Public static void main (string [] ARGs) throws solrserverexception, ioexception, parserconfigurationexception, saxexception {// Set SOLR.

1 Overview SOLR is an independent enterprise-class search application server that provides an API interface similar to Web-service. The user can submit a certain format XML file to the Search engine server through HTTP request, generate the index, or can make the lookup request through the HTTP GET operation, and obtain the return result of the XML format. This is mainly explained in this way through HTTP GET requests. First, we have to go through H
