Solr 添加文档时出错

Question

我创建了一个名为“fuzzy”的 solr 核心，但是我无法将文档添加到核心，我尝试使用以下 URL 添加文档:

http://localhost:8983/solr/Fuzzy/update?stream.body=<add><doc><field%20name="id">1</field><field%20name="original">München</field><field%20name="mutation">Munchen</field></doc></add>&commit=true

但我不断收到消息L

unknown UpdateRequestProcessorChain: add-unknown-fields-to-the-schema

我不确定为什么会收到此消息，在我的配置文件中:

<schemaFactory class="ClassicIndexSchemaFactory"/>

和 schema.xml :

<?xml version="1.0" encoding="UTF-8" ?>
<schema name="WikiData" version="1.5">
    <field name="id" type="int" indexed="true" stored="true" required="true" multiValued="false" />

    <field name="mutation" type="text_general" indexed="true" stored="true" />
    <field name="_version_" type="long" indexed="true" stored="true"/>
    <uniqueKey>id</uniqueKey>

Answer 1

默认的托管架构 the documentation建议应复制到 schema.xml 中，其中包含更新处理器请求链，在不使用托管架构时不需要该链。 (或者至少在 6.1.0 中是这样)

应从 solrconfig.xml 中删除或注释掉以下行:

<initParams path="/update/**">
  <lst name="defaults">
    <str name="update.chain">add-unknown-fields-to-the-schema</str> 
  </lst>
</initParams>

另一种选择可能是继续使用托管模式而不是经典方法，但将其设置为不可变，尽管我还没有测试过这一点，例如

<schemaFactory class="ManagedIndexSchemaFactory">
   <bool name="mutable">false</bool>
   <str name="managedSchemaResourceName">managed-schema</str>
</schemaFactory>
