solr手动查询的理解

solr查询是从每个shard中查询.然后再汇总出来.

solrCloud手动路由是通过路由字段来做路由的.

<field name="_route_" type="string"/>

索引创建的时候需要显示设置路由字段.

doc.addField("_route_","shard_x");

http://localhost:8980/solr/admin/collections?action=DELETE&name=trade_hand

http://localhost:8980/solr/admin/collections?action=CREATE&name=trade_hand

&collection.configName=tradeConf&router.name=implicit&shards=shard1,shard2

查询的时候

http://localhost:8980/solr/trade_hand/select?indent=on&q=shopNick:xxxx&wt=json&_route_=shard1

http://localhost:8980/solr/trade_hand/select?indent=on&q=shopNick:xxxx&wt=json&_route_=shard2

如果带上路由,solr就可以很精准地查询出数据.
