SOLR 建议器多字段自动完成

Question

我已经为一个字段设置了用于自动完成的建议器组件(它工作正常)，但我需要它用于多个字段，这可能吗？

我的 solrconfig xml:

<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.tst.TSTLookup</str>
      <str name="field">name</str>
      <float name="threshold">0.005</float>
      <str name="buildOnCommit">true</str>
    </lst>
  </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">10</str>
      <str name="spellcheck.collate">true</str>
    </lst>
    <arr name="components">
      <str>suggest</str>
    </arr>
  </requestHandler>

用户 copyfields 将多个字段组合成单个字段并在建议器中使用该字段 -

架构 -

<copyField source="name" dest="spell" />
<copyField source="other_name" dest="spell" />

建议者——

<str name="field">spell</str>
