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：

\n\n

http://localhost:8983/solr/Fuzzy/update?stream.body=<add><doc><field%20name="id">1</field><field%20name="original">M\xc3\xbcnchen</field><field%20name="mutation">Munchen</field></doc></add>&commit=true\n

\n\n

但我不断收到消息L

\n\n

\n

未知的 UpdateRequestProcessorChain：将未知字段添加到架构中

\n

\n\n

我不确定为什么会收到此消息，在我的配置文件中我有：

\n\n

<schemaFactory class="ClassicIndexSchemaFactory"/>

\n\n

和 schema.xml ：

\n\n

<?xml version="1.0" encoding="UTF-8" ?>\n<schema name="WikiData" version="1.5">\n    <field name="id" type="int" indexed="true" stored="true" required="true" multiValued="false" />\n    <field name="original" type="text_general" indexed="true" stored="true" />\n    <field name="mutation" type="text_general" indexed="true" stored="true" />\n    <field name="_version_" type="long" indexed="true" stored="true"/>\n    <uniqueKey>id</uniqueKey>\n\n    <fieldType name="int" class="solr.TrieIntField" precisionStep="0" positionIncrementGap="0"/>\n    <fieldType name="long" class="solr.TrieLongField" precisionStep="0" positionIncrementGap="0"/>\n    <fieldType name="text_general" class="solr.TextField" positionIncrementGap="100" multiValued="false">\n      <analyzer type="index">\n        <tokenizer class="solr.StandardTokenizerFactory"/>\n        <filter class="solr.LowerCaseFilterFactory"/>\n        <filter class="solr.PorterStemFilterFactory"/>\n      </analyzer>\n      <analyzer type="query">\n        <tokenizer class="solr.StandardTokenizerFactory"/>\n        <filter class="solr.LowerCaseFilterFactory"/>\n        <filter class="solr.PorterStemFilterFactory"/>\n      </analyzer>\n    </fieldType>\n</schema>\n

\n\n

solrconfig.xml：

\n\n

文档建议应复制的默认托管模式schema.xml包括不使用托管模式时不需要的更新处理器请求链。（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个，例如

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