Class DenormalizingPostProcessor

java.lang.Object

org.craftercms.search.service.impl.DenormalizingPostProcessor

All Implemented Interfaces:

DocumentPostProcessor<org.apache.solr.common.SolrInputDocument>

public class DenormalizingPostProcessor
extends Object
implements DocumentPostProcessor<org.apache.solr.common.SolrInputDocument>

Implementation of DocumentPostProcessor that can "denormalize" the parent and it's children documents, that means, it copies the fields from the parent to the children and the fields of the children to the parent. This is very helpful, for example, when you're doing a search on the children, but you need also certain fields from the parent.
