Question

我遇到了一个问题，试图让相关搜索结果使用带有和不带连字符的单词。我在“文本”字段中创建了两个文档，一个带有“wifi”，另一个带有“wi-fi”。

搜索“wifi”时，两个文档都会出现在搜索结果中，这很好。搜索“wi-fi”时，搜索结果中仅显示带有“wi-fi”的文档。

这是我的配置：

<field name="text" type="text" indexed="true" stored="true" omitNorms="true" />

<fieldType name="text" class="solr.TextField" positionIncrementGap="100" autoGeneratePhraseQueries="true">
  <analyzer type="index">
      <tokenizer class="solr.WhitespaceTokenizerFactory"/>
      <charFilter class="solr.HTMLStripCharFilterFactory"/>
      <filter class="solr.ASCIIFoldingFilterFactory" />
      <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/>
      <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="1" preserveOriginal="1" />
      <filter class="solr.LowerCaseFilterFactory"/>
      <filter class="solr.PorterStemFilterFactory"/>
      <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
  </analyzer>
  <analyzer type="query">
      <tokenizer class="solr.WhitespaceTokenizerFactory"/>
      <charFilter class="solr.HTMLStripCharFilterFactory"/>
      <filter class="solr.ASCIIFoldingFilterFactory" />
      <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/>
      <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="1" preserveOriginal="1" />
      <filter class="solr.LowerCaseFilterFactory"/>
      <filter class="solr.PorterStemFilterFactory"/>
      <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
  </analyzer>
</fieldType>

以下是analyzis的结果：https://www.evernote.com/shard/s7/sh/f1bab83a-7fd5-4bf3-9e67-239ea0c71441/98b1103577638734fb9335f755591b82/deep/0/Solr-Admin-(jeanfrancoiscote.egzakt.com).png

搜索“wi-fi”时调试查询。我无法找出为什么它找不到这两个文件：

感谢您的帮助。

Answer 1

您需要调整架构的分析方面。 debugQuery = true，Solr分析工具是您发现这类错误的朋友。

使用您的配置搜索wifi会产生以下查询：

wifi
"parsedquery_toString": "text:wifi",

和wi-fi

wi-fi
"parsedquery_toString": "text:\"(wi-fi wi) (fi wifi)\"",

我们配置的分析方面为wi-fi生成了无匹配的术语。

如果我们更改分析方面的过滤器而不生成单词部分：

  <filter class="solr.WordDelimiterFilterFactory" generateWordParts="0" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="1" preserveOriginal="1" />

我们获得了为wifi生成的以下搜索短语

parsedquery_toString": "text:wifi",

和wi-fi：

"parsedquery_toString": "text:wi-fi text:wifi"

从分析工具中找出wi-fi和wifi的索引术语

wi-fi, wi, fi, wifi
wifi

注意：text是此示例中的默认字段

使用/不使用连字符进行Solr搜索
