Solr拼写检查建议从不返回德语umlauts

我正在为一个德语页面执行solr拼写检查，但是我无法从那里接收德语umlauts

/拼写？拼写检查=on&spellcheck.count=1&spellcheck.collate=true&spellcheck.q=wärme“ 它永远不会返回umlauts：

我怎样才能做到这一点？ 以下是拼写检查的solrconfig.xml代码段：

<searchComponent name="spellcheck" class="solr.SpellCheckComponent">

    <str name="queryAnalyzerFieldType">text_general</str>

    <!-- Multiple "Spell Checkers" can be declared and used by this
         component
      -->

    <!-- a spellchecker built from a field of the main index -->
    <lst name="spellchecker">
      <str name="name">default</str>
      <str name="field">autocomplete</str>
      <str name="classname">solr.DirectSolrSpellChecker</str>
      <!-- the spellcheck distance measure used, the default is the internal levenshtein -->
      <str name="distanceMeasure">internal</str>
      <!-- minimum accuracy needed to be considered a valid spellcheck suggestion -->
      <float name="accuracy">0.25</float>
      <!-- the maximum #edits we consider when enumerating terms: can be 1 or 2 -->
      <int name="maxEdits">2</int>
      <!-- the minimum shared prefix when enumerating terms -->
      <int name="minPrefix">1</int>
      <!-- maximum number of inspections per result. -->
      <int name="maxInspections">10</int>
      <!-- minimum length of a query term to be considered for correction -->
      <int name="minQueryLength">1</int>
      <!-- maximum threshold of documents a query term can appear to be considered for correction -->
      <float name="maxQueryFrequency">0.01</float>
      <!-- uncomment this to require suggestions to occur in 1% of the documents
        <float name="thresholdTokenFrequency">.01</float>
      -->
    </lst>

    <!-- a spellchecker that can break or combine words.  See "/spell" handler below for usage -->
    <!--

      <str name="combineWords">true</str>
      <str name="breakWords">true</str>

拼写检查

直接使用索引中的术语-这意味着在存储术语之前对术语进行的任何分析都将反映在返回的建议中

您的字段类型将UMLAUT替换为其非UMLAUT版本，这就是返回的令牌。您希望对建议字段进行尽可能少的分析，这取决于您对建议如何工作的要求

当选择要查询此拼写检查器的字段时，您需要一个对其执行的分析相对较少的字段（特别是诸如词干分析之类的分析）
