我想myfield在solr中对字段应用不区分大小写的搜索.

我用Google搜索了一下,我发现,我需要应用LowerCaseFilterFactory字段类型和字段应该是solr.TextFeild.

我在我的应用程序中schema.xml重新索引数据,然后我的搜索似乎也区分大小写.

以下是我执行的搜索.

http://localhost:8080/solr/select?q=myfield:"cloud university"&hl=on&hl.snippets=99&hl.fl=myfield

以下是字段类型的定义

 <fieldType name="text_en_splitting" class="solr.TextField" positionIncrementGap="100" autoGeneratePhraseQueries="true">
      <analyzer type="index">
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <!-- in this example, we will only use synonyms at query time
        <filter class="solr.SynonymFilterFactory" synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/>
        -->
        <!-- Case insensitive stop word removal.
          add enablePositionIncrements=true in both the index and query
          analyzers to leave a 'gap' for more accurate phrase queries.
        -->
        <filter class="solr.StopFilterFactory"
                ignoreCase="true"
                words="stopwords_en.txt"
                enablePositionIncrements="true"
                />
        <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" …

我在尝试使用带连字符和不带连字符的单词获取相关搜索结果时遇到问题。我在“文本”字段中创建了两个文档，一个带有“wifi”，一个带有“wi-fi”。

搜索“wifi”时，两个文档都出现在搜索结果中，这很好。搜索“wi-fi”时，搜索结果中只会出现带有“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>
