我正在尝试仅针对测试实施法语的多语言搜索。 但是它没有用，我没有得到任何结果。有人可以帮助我。我在做什么错

这是我的法语结果。 solr法语搜索结果

Answer 1

问题在于，字段fr_Name的类型为string ，这意味着未对其进行分析或标记化，如果要搜索包含空格的内容（例如Apple Mac Book Pro ，则需要使用双引号将其完全匹配。 因此，查询"fq":"fr_Name":\\"Apple Mac Book Pro\\"应该适合您。

Solr Wiki上的一些参考资料：

字符串（UTF-8编码的字符串或Unicode）。 字符串用于较小的字段，不会以任何方式标记或分析。 它们的硬限制略小于32K。

Answer 2

添加此字段类型

<fieldType name="text_fr" class="solr.TextField" positionIncrementGap="100">
      <analyzer>
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.ElisionFilterFactory" articles="lang/contractions_fr.txt" ignoreCase="true"/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.StopFilterFactory" format="snowball" words="lang/stopwords_fr.txt" ignoreCase="true"/>
        <filter class="solr.FrenchLightStemFilterFactory"/>
      </analyzer>
    </fieldType>

它为我工作
