配置 Solr 以使用 UUID 作为键 [英] Configuring Solr to use UUID as a key
问题描述
我正在尝试配置 Solr 4 以使用 UUID,但到目前为止我没有成功
I am trying to configure Solr 4 to work with UUID and so far I am unsuccessful
通过阅读文档,我看到了两种不同的方式来配置 schema.xml 以使用 UUID(两者都不起作用)
From reading the documentation I have seen two different ways to configure schema.xml to work with UUID (both do not work)
对于两者我都需要写
<fieldType name="uuid" class="solr.UUIDField" indexed="true" />
选项 1:添加:
<field name="id" type="uuid" indexed="true" stored="true" default="NEW" multiValued="false"/>
并确保删除该行
<uniqueKey>id</uniqueKey>
选项 2添加:
<field name="id" type="uuid" indexed="true" stored="true" required="true" multiValued="false" />
两个选项都无法正常工作并返回org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: 初始化 QueryElevationComponent 时出错.
Both options are not working correctly and returning org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error initializing QueryElevationComponent.
我还尝试使用以下配置向 colrconfig.xml 文件添加一行:
I also tried adding a row to the colrconfig.xml file with the configuration:
<updateRequestProcessorChain name="uuid">
<processor class="solr.UUIDUpdateProcessorFactory">
<str name="fieldName">uniqueKey</str>
</processor>
<processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>
谢谢,

推荐答案
经过一番努力,这里是解决方案:
After some work here is the solution:
在 schema.xml 中,添加(或编辑)字段字段
In schema.xml, add (or edit) the field field
<field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false" />
在 solr 配置中,更新链并将链添加到处理程序中(例如:for/update/extract):
In solr config, update the chain and add the chain to the handlers (Example: for /update/extract):
<updateRequestProcessorChain name="uuid">
<processor class="solr.UUIDUpdateProcessorFactory">
<str name="fieldName">id</str>
</processor>
<processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>`
<requestHandler name="/update/extract"
startup="lazy"
class="solr.extraction.ExtractingRequestHandler" >
<lst name="defaults">
<str name="lowernames">true</str>
<str name="uprefix">ignored_</str>
<str name="captureAttr">true</str>
<str name="fmap.a">links</str>
<str name="fmap.div">ignored_</str>
<str name="update.chain">uuid</str>
</lst>
</requestHandler>
