Solr:QueryElevationComponent 需要 StrField uniqueKeyField 错误 [英] Solr: QueryElevationComponent requires StrField uniqueKeyField error

问题描述

我最近安装了 solr.示例索引(在 apache-solr-#.#.#examplesolr 中找到)似乎有效，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，当我尝试通过将 schema.xml 内容替换为 (取自 这里):

I recently installed solr. The example index (found at apache-solr-#.#.#examplesolr) seems to work, and, once copied to my solr home directory, I am able to access it through the admin pages. However when I try to implement a new index by replacing the schema.xml content with (taken from here):

<?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 必须使用 StrField 类型来实现(我很难相信实际上是这样?)):

I am receiving a configuration error, which seems to suggest that the uniqueKeyField must be implemented with a StrField type (something I find hard to believe is actually the case?)):

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

我的谷歌搜索几乎没有帮助，所以我希望这里可能有人遇到过这个问题和/或有一些解决方法的想法?

My googling has turned up very little to help, so I am hoping there might be someone around here who might have come across this issue and/or have some ideas how to resolve it?

提前感谢您的建议，Bea.

Thanks in advance for any advice, Bea.

推荐答案

是的，目前 QueryElevationComponent 需要一个字符串唯一键.这个限制是在 Solr wiki 中记录.

Yes, at the moment QueryElevationComponent requires a string unique key. This limitation is documented in the Solr wiki.

这是 JIRA 项目中的问题.
