Question

例如，我使用文本索引了两个文档：

doc1 - Test—emdash

doc2 - Test without emdash

我正在查询“—emdash”正在返回这两个文档，我应该如何配置以便它只返回带有完整短语的文档？

用于索引的字段类型为textgen

<fieldType name="textgen" class="solr.TextField" positionIncrementGap="100">
  <analyzer type="index">
    <tokenizer class="solr.WhitespaceTokenizerFactory"/>
    <!-- <filter class="solr.ASCIIFoldingFilterFactory"/> -->
    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" />
    <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="0"/>
    <filter class="solr.LowerCaseFilterFactory"/>
  </analyzer>
  <analyzer type="query">
    <tokenizer class="solr.WhitespaceTokenizerFactory"/>
    <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
    <filter class="solr.StopFilterFactory"
            ignoreCase="true"
            words="stopwords.txt"
            enablePositionIncrements="true"
            />
    <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0" splitOnCaseChange="0"/>
    <filter class="solr.LowerCaseFilterFactory"/>
  </analyzer>
</fieldType>

Answer 1

1）删除WordDelimiter过滤器 2）添加映射字符过滤器：＆＃34; - ＆＃34; =＆GT; ＆＃34; - ＆＃34;

Solr - 包括短语搜索中的emdash
