solr suggester没有结果

Question

我尝试为 solr 设置一个建议器。我有多个信息字段。这是一个例子（字段：值）：

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

现在，我希望 solr 能够在输入时获取文档，无论用户是开始输入基因名称或 ID 还是...

solrconfig.xml 中的建议者看起来像这样（或多或少来自示例 copy/paste）：

<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是按照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"}]}},

我试过的查询没有return任何结果：

suggest?q=egfr

我不知道如何解决问题，我想我还没有完全理解建议请求会发生什么。

Answer 1

建议者实际上做了 return 结果，但由于 suggestAnalyzerFieldType 已设置为 string，查询区分大小写。将字段类型更改为我自己定义的字段类型 mytext 解决了这个问题。
