Solr拼写检查器没有返回任何结果

Question

我正在开发一个需要我第一次使用Solr的应用程序.我把它设置,索引正确的数据和查询,我想,但我不能似乎得到了拼写检查部件工作正常.无论我查询什么,拼写检查器都不会返回任何建议.我已经包含了solrconfig和schema.xml的相关部分.

schema.xml中

<fieldType name="textSpell" class="solr.TextField" positionIncrementGap="100" omitNorms="true">
  <analyzer type="index">
    <charFilter class="solr.HTMLStripCharFilterFactory"/>
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.StandardFilterFactory"/>
  </analyzer>
  <analyzer type="query">
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true"  expand="true"/>
    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.StandardFilterFactory"/>
  </analyzer>
</fieldType>

<!-- CUT -->

<field name="spell" type="textSpell" indexed="true" stored="true" />

solrconfig.xml中

<requestHandler name="/select" class="solr.SearchHandler">
   <lst name="defaults">
     <str name="defType">edismax</str>
     <str name="spellcheck.dictionary">default</str>

  <str name="queryAnalyzerFieldType">textSpell</str>
</searchComponent>

当我去http://localhost:8983/solr/select/?q=query&spellcheck.build=true看看/ path/to/my/spell/index中生成的文件时,有一个segments.gen和一个segments_1,它们都只包含几个字节的二进制数据.然后,当我输入查询并附&spellcheck=true加到查询字符串时,无论我的查询是什么,我都不会得到任何建议:

<lst name="spellcheck">
  <lst name="suggestions"/>
</lst>

知道这里发生了什么吗？

我不久前解决了这个问题，但据我回忆，问题是我使用多个<copyField/>指令将数据复制到“拼写”字段，但我没有multiValued="true"在该字段上设置。当我将拼写检查字段设置为多值时，它就像一个魅力！
