Solr 建议器 - 在Suggest.cfq 中查找子字符串

如何解决Solr 建议器 - 在Suggest.cfq 中查找子字符串

我正在实现一个 Solr 请求处理程序来创建一个建议者。作为 contextField，我使用的字段可以包含多个值，如果 suggest.cfq 参数匹配这些值中的至少一个或一部分，我希望能够搜索建议。

<requestHandler name="/searchSuggester" class="solr.SearchHandler" startup="lazy">
  <lst name="defaults">    
    <str name="suggest">true</str>
    <str name="suggest.count">10</str>
    <str name="suggest.dictionary">suggesterdisctionary</str>
    <!-- str name="highlight">false</str -->
    <!-- str name="suggest.cfq">UNCOMMNET_FOR_DEBUG</str -->
  </lst>
  <arr name="components">
    <str>suggest</str>
  </arr>
</requestHandler>

<searchComponent name="suggest" class="solr.SuggestComponent">
  <lst name="suggester">
    <str name="name">suggesterdisctionary</str>
    <str name="lookupImpl">AnalyzingInfixLookupFactory</str>
    <str name="dictionaryImpl">DocumentDictionaryFactory</str>
    <str name="field">test_all</str>
    <str name="contextField">multiple_suggest</str>
    <str name="suggestAnalyzerFieldType">text_general</str>
    <str name="buildOnStartup">false</str>
  </lst>
</searchComponent>

在不使用 suggest.cfq 参数的情况下寻找通用建议

http://HOST:8983/solr/COLLECTION/searchSuggester?suggest.q=my_word

但是我如何添加 suggest.cfq 以匹配例如任何值？（这只是为了调试）并匹配包含在我的 multiple_suggest 多值字段中的特定字符串？

我试过了

http://HOST:8983/solr/COLLECTION/searchSuggester?suggest.q=my_word&suggest.cfq=*

和

http://HOST:8983/solr/COLLECTION/searchSuggester?suggest.q=my_word&suggest.cfq=*sub*

但第一个返回错误 "msg": "Failed to parse query: null" 而第二个不返回任何建议
