如何在solr中编写嵌套的schema.xml

How to write nested schema.xml in solr

schema.xml中的文档显示

The document in schema.xml says

<!-- points to the root document of a block of nested documents. Required for nested
document support, may be removed otherwise
-->
<field name="_root_" type="string" indexed="true" stored="false"/>

http://svn.apache.org/viewvc/lucene/dev/trunk/solr/example/solr/ collection1 / conf / schema.xml？view = markup

可用于

https://cwiki.apache.org/confluence/display/solr / Other + Parsers＃OtherParsers-BlockJoinQueryParsers

嵌套以下项目的schema.xml是什么：

What will be schema.xml for nesting the following items:

• 人员字符串


• 地址
  
  
  
  • 城市字符串
  
  
  • 邮政编码字符串
  
  

  推荐答案

  I知道这是一个老问题，但是我遇到了类似的问题。修改我的解决方案后，您需要添加到schema.xml中的字段如下：

  I know this is an old question, but I ran into a similar issue. Modifying my solution for yours, the fields you need to add to your schema.xml are as follows:

   <field name="person" type="string" indexed="true" stored="true" />
   <field name="address" type="string" indexed="true" stored="true" multiValued="true"/> 
   <field name="address.city" type="string" indexed="true" stored="true" />
   <field name="address.postcode" type="string" indexed="true" stored="true" />
  

  然后，在运行它时，您应该可以将以下JSON添加到Solr实例中并查看匹配查询中的输出：

  Then when you run it you should be able to add the following JSON to your Solr instance and see the matching output in the query:

  {
    "person": "John Smith",
    "address": {
        "city": "San Diego",
        "postcode": 92093
      }
  }
