Class SolrSearchServiceImpl

java.lang.Object

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

All Implemented Interfaces:

SearchService, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.InitializingBean

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

This constructor serves to mimic the one which takes in one SolrServer argument. By having this and then simply disregarding the second parameter, we can more easily support 2-core Solr configurations that use embedded/standalone per environment.

Parameters:

Parameters:

namedFacetMap -

response -

sortFacetResults

protected void sortFacetResults(Map<String,SearchFacetDTO> namedFacetMap)

Invoked to sort the facet results. This method will use the natural sorting of the value attribute of the facet (or, if value is null, the minValue of the facet result). Override this method to customize facet sorting for your given needs.

Parameters:

facet -

request -

Returns:

whether or not the facet parameter is available

sanitizeQuery

protected String sanitizeQuery(String query)
