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">

<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.
