Question

我创建了一个名为“模糊”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

但我一直收到消息L

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

我不知道为什么我收到此消息，在我的配置文件中我有：

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

    <fieldType name="int" class="solr.TrieIntField" precisionStep="0" positionIncrementGap="0"/>
    <fieldType name="long" class="solr.TrieLongField" precisionStep="0" positionIncrementGap="0"/>
    <fieldType name="text_general" class="solr.TextField" positionIncrementGap="100" multiValued="false">
      <analyzer type="index">
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.PorterStemFilterFactory"/>
      </analyzer>
      <analyzer type="query">
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.PorterStemFilterFactory"/>
      </analyzer>
    </fieldType>
</schema>

Answer 1

the documentation建议应将其复制到schema.xml的默认托管架构包括不使用托管架构时不需要的更新处理器请求链。（或至少在6.1.0中也是如此）

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>

另一种方法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，尽管我还没有对此进行测试，例如

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