配置拼音搜索:

復制pinyin4j-2.5.0.jar、pinyinAnalyzer.jar這兩個jar包到solr-8.5.0/server/solr-webapp/webapp/WEB-INF/lib目錄下修改solr-8.5.0/server/solr/conf下的managed-schema

在文件中增加如下內容：這里設置fieldType的name為 text_pinyin

<fieldType name="text_pinyin" class="solr.TextField" positionIncrementGap="0">
<analyzer type="index">
<tokenizer class="org.apache.lucene.analysis.ik.IKTokenizerFactory"/>
<filter class="com.shentong.search.analyzers.PinyinTransformTokenFilterFactory" minTermLenght="2"/>
<filter class="com.shentong.search.analyzers.PinyinNGramTokenFilterFactory" maxGram="20" minGram="1"/>
</analyzer>
<analyzer type="query">
<tokenizer class="org.apache.lucene.analysis.ik.IKTokenizerFactory"/>
<filter class="com.shentong.search.analyzers.PinyinTransformTokenFilterFactory" minTermLenght="2"/>
<filter class="com.shentong.search.analyzers.PinyinNGramTokenFilterFactory" maxGram="20" minGram="1"/>
</analyzer>
</fieldType>

配置SuggestComponent:SuggestComponent 為用戶提供查詢術語的自動建議.該建議器的主要特點是：查找實現可插拔性,術語詞典可插拔性，使您可以靈活選擇詞典實現, 分布式支持.

第一步是添加一個搜索組件solrconfig.xml并告訴它使用 SuggestComponent。

<searchComponent name="suggest" class="solr.SuggestComponent">
  <lst name="suggester">
    <str name="name">mySuggester</str>
    <str name="lookupImpl">FuzzyLookupFactory</str>
    <str name="dictionaryImpl">DocumentDictionaryFactory</str>
    <str name="field">cat</str>
    <str name="weightField">price</str>
    <str name="suggestAnalyzerFieldType">string</str>
    <str name="buildOnStartup">false</str>
  </lst>
</searchComponent>

添加搜索組件后，必須將請求處理程序添加到solrconfig.xml

<requestHandler name="/suggest" class="solr.SearchHandler" startup="lazy">
  <lst name="defaults">
    <str name="suggest">true</str>
    <str name="suggest.count">10</str>
  </lst>
  <arr name="components">
    <str>suggest</str>
  </arr>
</requestHandler>

配置拼寫檢查:

SpellCheck 組件旨在根據其他類似術語提供內聯查詢建議.

這些建議的基礎可以是 Solr 中字段中的術語、外部創建的文本文件或其他 Lucene 索引中的字段。

solrconfig.xml使用以下配置

<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
  <lst name="spellchecker">
    <str name="name">default</str>
    <str name="field">name</str>
    <str name="classname">solr.DirectSolrSpellChecker</str>
    <str name="distanceMeasure">internal</str>
    <float name="accuracy">0.5</float>
    <int name="maxEdits">2</int>
    <int name="minPrefix">1</int>
    <int name="maxInspections">5</int>
    <int name="minQueryLength">4</int>
    <int name="maxQueryLength">40</int>
    <float name="maxQueryFrequency">0.01</float>
    <float name="thresholdTokenFrequency">.01</float>
  </lst>
</searchComponent>

使用FileBasedSpellChecker外部文件作為拼寫詞典

<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
  <lst name="spellchecker">
    <str name="classname">solr.FileBasedSpellChecker</str>
    <str name="name">file</str>
    <str name="sourceLocation">spellings.txt</str>
    <str name="characterEncoding">UTF-8</str>
    <str name="spellcheckIndexDir">./spellcheckerFile</str>
 </lst><
/searchComponent>
