Solr:QueryElevationComponent需要StrField uniqueKeyField错误

Question

我最近安装了solr.示例索引(在apache-solr中找到 - #.#.#\ example\solr)似乎可以工作,并且一旦复制到我的solr主目录,我就可以通过管理页面访问它.但是,当我尝试通过替换schema.xml内容(从此处获取)来实现新索引时:

<?xml version="1.0" encoding="UTF-8" ?> 
  <schema name="example" version="1.2">
  <types>
      <fieldType name="string" class="solr.StrField" sortMissingLast="true" omitNorms="true" /> 
      <fieldType name="int" class="solr.TrieIntField" precisionStep="0" omitNorms="true" positionIncrementGap="0" /> 
      <fieldType name="date" class="solr.TrieDateField" omitNorms="true" precisionStep="0" positionIncrementGap="0" /> 
      <fieldType name="text" class="solr.TextField" positionIncrementGap="100">
          <analyzer type="index">
              <tokenizer class="solr.WhitespaceTokenizerFactory" /> 
              <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" /> 
              <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="1" /> 
              <filter class="solr.LowerCaseFilterFactory" /> 
              <filter class="solr.SnowballPorterFilterFactory" language="English" protected="protwords.txt" /> 
          </analyzer>
        <analyzer type="query">
          <tokenizer class="solr.WhitespaceTokenizerFactory" /> 
          <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true" /> 
          <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" /> 
          <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0" splitOnCaseChange="1" /> 
          <filter class="solr.LowerCaseFilterFactory" /> 
          <filter class="solr.SnowballPorterFilterFactory" language="English" protected="protwords.txt" /> 
        </analyzer>
      </fieldType>
      </types>
  <fields>
      <field name="fileid" type="int" indexed="true" stored="true" required="true" /> 
      <field name="doctext" type="text" indexed="true" stored="false" required="false" /> 
      <field name="title" type="text" indexed="true" stored="false" required="false" /> 
      <field name="datecreated" type="date" indexed="true" stored="false" /> 
  </fields>
  <uniqueKey>fileid</uniqueKey> 
  <defaultSearchField>doctext</defaultSearchField> 
  <solrQueryParser defaultOperator="OR" /> 
  </schema>

我收到一个配置错误,这似乎表明uniqueKeyField必须用StrField类型实现(我觉得很难相信的是这种情况？)):

"HTTP状态500 - solr配置中的严重错误.... org.apache.solr.common.SolrException:QueryElevationComponent要求架构在org.apache.solr.handler.component.QueryElevationComponent.inform中使用StrField实现uniqueKeyField( QueryElevationComponent.java:157)atg.apache.solr.core.SolrResourceLoader.inform(SolrResourceLoader.java:508)at ..."

我的谷歌搜索引起了很少的帮助,所以我希望周围可能有人可能遇到过这个问题和/或有一些想法如何解决它？

提前感谢任何建议,Bea.

是的,目前QueryElevationComponent需要一个字符串唯一键.Solr wiki中记录了此限制.

这是 JIRA项目中的问题.
