solr cloud 之添加，删除，更新Document

xingyu655

 
    搭建完成solr cloud的集群之后，接下来的工作就是需要向集群中导入数据，之后可能要更新数据，或者删除数有，假设有有一个服务的schema中的field是这样定义的：
 

<fields>
<field name="id"     type="string"  indexed="true" stored="true" required="true" />
<field name="name"   type="text"    indexed="true" stored="true" required="true" />
<field name="age" type="string"  indexed="true" stored="true" />
<field name="comefrom" type="string"  indexed="true" stored="true" />
<field name="_version_" type="long" indexed="true" stored="true"/>
</fields>
   

   新增记录

 
   首先可以通过最简便的方式向集群中添加数据，在cmd命令行中敲入以下命令：
 

java -Durl=http://localhost:8983/solr/update -jar   post.jar terminator.xml
   terminator.xml 文件的内容是：
 

<add>
<doc>
<field name="id">9999999</field>
<field name="name">abcdefghijkmn</field>
<field name="source">kkkkkkkkkkkkkkkkkkkkk</field>
<!-- Join -->
<field name="shape">gggggggggggggg</field>
<field name="ptvector">llllllllllllllll</field>
<field name="quad">quadquadquadquadquad</field>
<field name="geohash">geohashgeohashgeohashgeohashgeohashgeohash</field>
</doc>
<doc>
<field name="id">9999998</field>
<field name="name">abcdefghijkmn</field>
<field name="source">kkkkkkkkkkkkkkkkkkkkk</field>
<!-- Join -->
<field name="shape">gggggggggggggg</field>
<field name="ptvector">llllllllllllllll</field>
<field name="quad">quadquadquadquadquad</field>
<field name="geohash">geohashgeohashgeohashgeohashgeohashgeohash</field>
</doc>
<doc>
<field name="id">9999997</field>
<field name="name">abcdefghijkmn</field>
<field name="source">kkkkkkkkkkkkkkkkkkkkk</field>
<!-- Join -->
<field name="shape">gggggggggggggg</field>
<field name="ptvector">llllllllllllllll</field>
<field name="quad">quadquadquadquadquad</field>
<field name="geohash">geohashgeohashgeohashgeohashgeohashgeohash</field>
</doc>
<doc>
<field name="id">9999996</field>
<field name="name">abcdefghijkmn</field>
<field name="source">kkkkkkkkkkkkkkkkkkkkk</field>
<!-- Join -->
<field name="shape">gggggggggggggg</field>
<field name="ptvector">llllllllllllllll</field>
<field name="quad">quadquadquadquadquad</field>
<field name="geohash">geohashgeohashgeohashgeohashgeohashgeohash</field>
</doc>
</add>

 
 
成功执行命令：
 

D:\download\solr-4.1.0\solr-4.1.0\example\exampledocs>
java -Durl=http://localhost:8983/solr/update -jar post.jar terminator.xm
SimplePostTool version 1.5 Posting files to base url http://localhost:8983/solr/update using content-type application/xml..
POSTing file terminator.xml 1 files indexed. COMMITting Solr index changes to http://localhost:8983/solr/update..
　　Document的share规则：
　　通过以上命令，成功将4条记录插入到了集群中。在solr节点的查询页面进行查询，显示结果集如下：

</response>
　　大家会发现在输出的结果集上有一个[size=1em][shard]字段，标识该条记录存储在集群中的哪个share分区中。要在结果集中shard字段可以通过设置 fl=*,[shard]做到。从[size=1em][shard]属性的值[size=1em]来看四条记录被均匀的分布到了两个share中。

[size=1em]更新数据

[size=1em]删除数据
　　java -Ddata=args  -jar post.jar '<delete><id>[size=1em]9999996</id></delete>'
　　或者
　　java -Ddata=args  -jar post.jar '<delete><query>id:9999996</query></delete>'
　　[size=1em]经过测试，以上两条命令都可以成功删除id为[size=1em]9999996的那条记录。
