Class SolrSearchServiceImpl

java.lang.Object

org.broadleafcommerce.core.search.service.solr.SolrSearchServiceImpl

All Implemented Interfaces:

SearchService, org.springframework.beans.factory.DisposableBean

public class SolrSearchServiceImpl
extends Object
implements SearchService, org.springframework.beans.factory.DisposableBean

An implementation of SearchService that uses Solr. Note that prior to 2.2.0, this class used to contain all of the logic for interaction with Solr. Since 2.2.0, this class has been refactored and parts of it have been split into the other classes you can find in this package.
