当我向我的 Suggester 组件输入一个包含多个单词的查询时，我得到了每个单词的单独结果。问题在这里得到了很好的解释：当查询包含多个术语时，如何让 Solr 自动完成整个短语？

唯一的区别是，我有一个基于字典文件的建议器，而不是索引字段。上述链接中解释的解决方案以及许多其他解决方案均无效

这是配置：

<searchComponent class="solr.SpellCheckComponent" name="suggest">
    <lst name="spellchecker">
        <str name="name">suggest</str>
        <str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
        <str name="lookupImpl">org.apache.solr.spelling.suggest.fst.AnalyzingInfixLookupFactory</str>
        <str name="buildOnCommit">true</str>
        <str name="suggestAnalyzerFieldType">text_suggest</str>
        <str name="sourceLocation">suggestionsFull.txt</str>
    </lst>
    <str name="queryAnalyzerFieldType">text_suggest</str>
    <!-- <queryConverter name="queryConverter" class="org.apache.solr.spelling.SuggestQueryConverter"/> -->
</searchComponent>

<requestHandler class="org.apache.solr.handler.component.SearchHandler" name="/suggest">
    <lst name="defaults">
        <str name="spellcheck">true</str>
        <str name="spellcheck.dictionary">suggest</str>
        <str name="spellcheck.onlyMorePopular">true</str>
        <str name="spellcheck.count">5</str>
        <str name="spellcheck.collate">false</str>
    </lst>
    <arr name="components">
        <str>suggest</str>
    </arr>
</requestHandler>

架构.xml

<fieldType name="text_suggest" class="solr.TextField" positionIncrementGap="100">
    <analyzer>
        <tokenizer class="solr.KeywordTokenizerFactory"/>
        <filter class="solr.TurkishLowerCaseFilterFactory"/>
        <filter class="solr.TrimFilterFactory"/>
    </analyzer>
</fieldType>

我也使用spellcheck.q参数而不是q

http://localhost:8983/solr/collection1/suggest?spellcheck.q=bu+bir&wt=json&indent=true

我究竟做错了什么？

最后我找到了解决方案：

看起来即使您从文件而不是索引字段构建建议字典，您也必须在 solrconfig.xml 中指定索引字段。因此，从我们已经创建的字段类型schema.xml创建一个虚拟字段：text_suggest

<field name="text_suggest" type="text_suggest" indexed="false" stored="false" />

然后在solrconfig.xml添加<str name="field">text_suggest</str>行中searchComponent：

<searchComponent class="solr.SpellCheckComponent" name="suggest">
       <lst name="spellchecker">
          <str name="name">suggest</str>
          <str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
          <str name="lookupImpl">org.apache.solr.spelling.suggest.fst.AnalyzingInfixLookupFactory</str>
          <str name="buildOnCommit">true</str>
          <str name="suggestAnalyzerFieldType">text_suggest</str>
          <str name="field">text_suggest</str>
          <str name="sourceLocation">suggestionsFull.txt</str>
       </lst>
    </searchComponent>

重新启动solr，你就完成了！
