WhenweuseSpringDataSolr,wehaveMulticoreSolrServerFactory

http://projects.spring.io/spring-data-solr/

@SolrDocument(solrCoreName=“core1”)

classBean1{

...

}

factory=newMulticoreSolrServerFactory(newHttpSolrServer(“http://host:8983”));

SolrServersolrServer=factory.getSolrServer(Bean1.class);

{!joinfrom=fromFieldto=toFieldfromIndex=fromCoreName}fromQuery

Have2cores

brands{id,name}

products{id,name,brand_id}

BRANDS:{1,Apple}{2,Alibaba}{3,Hundsun}

PRODUCTS:{1,iPhone,1},{2,iPad,1}...

http://host:8983/solr/brands/select?q=*:*&fq={!joinfrom=brand_idto=idfromIndex=products}name:iPad

Itwilltranslatestosomethinglike:

SELECTb.*FROMbrandsbINNERJOINproductspONb.id=p.brand_idWHEREp.name=“iPad”;

{id:“1”,name:”Apple"}
