Question

尝试使用solr.UUIDField生成uniqueKey字段。

<fieldType name="uuid" class="solr.UUIDField" indexed="true" />


<field name="uid" type="uuid" indexed="true" stored="true" default="NEW" />

<uniqueKey>uid</uniqueKey>

但由于某种原因，它不起作用。

错误讯息：

在我做出了答案中的leoh建议的更改后，我收到了以下错误消息：

我也忘了提到它在使用dataimporthandler时我收到了错误信息。

我尝试删除以下内容，但之后没有任何内容编入索引：

<searchComponent name="elevator" class="org.apache.solr.handler.component.QueryElevationComponent" >
    <!-- pick a fieldType to analyze queries -->
    <str name="queryFieldType">string</str>
    <str name="config-file">elevate.xml</str>
</searchComponent>

要在solr 4.6中配置uuid字段，您可能需要以下配置

<!--schema.xml-->

<fieldType name="uuid" class="solr.UUIDField" indexed="true" />

<field name="id" type="uuid" indexed="true" stored="true" required="true" />

<uniqueKey>id</uniqueKey>

<!--solrconfig.xml-->
<updateRequestProcessorChain name="uuid">
    <processor class="solr.UUIDUpdateProcessorFactory">
      <str name="fieldName">id</str>
    </processor>
    <processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>


 <requestHandler name="/update" class="solr.UpdateRequestHandler">
       <lst name="defaults">
         <str name="update.chain">uuid</str>
       </lst>
</requestHandler>

Answer 2

对于第二个错误“init failure：”，您需要修改elevate.xml文件中的uid。提升文件的默认路径是

@ SOLR_HOME\example\example-DIH\solr\solr\conf

可能你的文件路径可能不同。

如果您想知道elevate.xml文件的确切位置，请附上您的elevate.xml文件。

SOLR uniqueKey与solr.UUIDField
