solr - solr 建议器没有结果

问题描述

我尝试为 solr 设置一个建议器。我有多个包含信息的字段。这是一个示例（字段：值）：

基因：EGFR
cac：abf.4c3C
ccd：frl.dlgfX
主题：EGFR - 此更改
id：7390

现在，我希望 solr 能够在键入时获取文档，无论用户是否开始键入基因名称或 id 或...

solrconfig.xml 中的建议器看起来像这样（或多或少从示例中复制/粘贴）：

<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">suggest_muripedia</str>
  </lst>
  <arr name="components">
    <str>suggest</str>
  </arr>
</requestHandler>

<!-- Suggester component -->
<searchComponent name="suggest" class="solr.SuggestComponent">
  <lst name="suggester">
    <str name="name">suggest_muripedia</str>
    <str name="lookupImpl">FuzzyLookupFactory</str>
    <str name="dictionaryImpl">DocumentDictionaryFactory</str>
    <str name="field">_text_cf</str>
    <str name="weightField">subject</str>
    <str name="suggestAnalyzerFieldType">string</str>
    <str name="buildOnStartup">false</str>
  </lst>
</searchComponent>

_text_cf 是由上述字段的复制规则填充的字段，定义如下：

{
      "name":"_text_cf",
      "type":"mytext",
      "multiValued":true,
      "indexed":true,
      "stored":true},

字段类型mytext看起来像这样

 {
      "name":"mytext",
      "class":"solr.TextField",
      "positionIncrementGap":"100",
      "multiValued":true,
      "indexAnalyzer":{
        "tokenizer":{
          "class":"solr.PatternTokenizerFactory",
          "pattern":"-"},
        "filters":[{
            "class":"solr.TrimFilterFactory"},
          {
            "class":"solr.StopFilterFactory",
            "words":"stopwords.txt",
            "ignoreCase":"true"},
          {
            "class":"solr.LowerCaseFilterFactory"}]},
      "queryAnalyzer":{
        "tokenizer":{
          "class":"solr.PatternTokenizerFactory",
          "pattern":"-"},
        "filters":[{
            "class":"solr.TrimFilterFactory"},
          {
            "class":"solr.StopFilterFactory",
            "words":"stopwords.txt",
            "ignoreCase":"true"},
          {
            "class":"solr.SynonymGraphFilterFactory",
            "expand":"true",
            "ignoreCase":"true",
            "synonyms":"synonyms.txt"},
          {
            "class":"solr.LowerCaseFilterFactory"}]}},

我尝试过的查询没有返回任何结果：

suggest?q=egfr

我不知道如何排除故障，我想我还没有完全理解建议请求会发生什么。
