Solr建议者只添加多值字段中的第一个值来建议字典

Question

我使用Solr Suggest组件返回多值存储的字段的建议。 问题：只有文档的多值字段的第一个条目才会添加到字典数据库中。

<searchComponent name="suggest" class="solr.SuggestComponent">
    <lst name="suggester">
      <str name="name">suggestSkill</str>
      <str name="lookupImpl">org.apache.solr.spelling.suggest.jaspell.JaspellLookupFactory</str>      <!-- org.apache.solr.spelling.suggest.fst -->
      <str name="dictionaryImpl">DocumentDictionaryFactory</str>     <!-- org.apache.solr.spelling.suggest.HighFrequencyDictionaryFactory --> 
      <str name="field">skills</str>
      <str name="weightField">skills</str>
      <str name="storeDir">/usr/share/solr/live/solr/collection1/suggest/</str>
      <str name="suggestAnalyzerFieldType">string</str>
      <str name="buildOnCommit">true</str>
    </lst>
  </searchComponent>

  <requestHandler name="/suggest" class="solr.SearchHandler" startup="lazy">
    <lst name="defaults">
      <str name="suggest">true</str>
      <str name="suggest.count">10</str>
     <str name="suggest.dictionary">suggestSkill</str>
    </lst>
    <arr name="components">
      <str>suggest</str>
    </arr>
</requestHandler>

想象一下以下文件：

 "docs": [
      {
        "id": "100444001",
        "firstName": "Piet",
        "lastName": "Huysentruyt",
        "skills": [
          "mongoDB",
          "angularJS",
          "Java ServerPages",
          "mongoDB",
          "angularRD"
        ],
        "_version_": 1482216060554838000
      },
      {
        "id": "104444",
        "firstName": "Bomas",
        "lastName": "Banciaux",
        "skills": [
          "bower",
          "Front-End Engineering"
        ],
        "_version_": 1482216060556935200
      }]

在搜索技能建议时，/ suggest字段中只能使用bower和mongo。甚至在suggest.build命令之后。有什么想法吗？

更新：自Solr第5版起，建议器现在适用于多值字段
