只需要在url中添加shards.info=true和shards=host:port/base_url[,host:port/base_url]
举例
http://localhost:8983/solr/media/select?q=title:"地球"&wt=json&indent=true&fl=title&shards.info=true&shards=localhost:8983/solr/media,localhost:8983/solr/game
注意:这会使后续所有查询的shards.info=true,如果后续查询不需要跨core,需要显式地添加shards.info=false
