solr5.3的spellcheck功能

1.增加schema.xml中的檢查字段。

<field name="title" type="text_cn" indexed="true" stored="true" required="false" multiValued="false" />

<fieldType name="text_cn" class="solr.TextField">
        <analyzer type="index">
            <!--使用HanLP分析器進行分詞 -->
            <tokenizer class="com.hankcs.lucene.HanLPTokenizerFactory" mode="max-word"/>
            <!-- 將分詞結果同時轉換爲拼音 -->
            <filter  class="com.shentong.search.analyzers.PinyinTransformTokenFilterFactory"  minTermLenght="2" />
             <filter    class="com.shentong.search.analyzers.PinyinNGramTokenFilterFactory"    minGram="6" maxGram="20" />
        </analyzer>
        <analyzer type="query">
            <tokenizer class="com.hankcs.lucene.HanLPTokenizerFactory" mode="max-word"/>
            <filter class="com.hankcs.lucene.analysis.synonym.SynonymFilterFactory"  synonyms="synonyms.txt" ignoreCase="true" expand="true" format="word2vec"/>
            <filter  class="com.shentong.search.analyzers.PinyinTransformTokenFilterFactory"  minTermLenght="2" />
            <filter    class="com.shentong.search.analyzers.PinyinNGramTokenFilterFactory"    minGram="6" maxGram="20" />
        </analyzer>
    </fieldType>

2.修改solrconfig.xml內容：

<searchComponent name="spellcheck" class="solr.SpellCheckComponent">  
    <!--<str name="queryAnalyzerFieldType">text_cn</str>  --> 
    <!-- a spellchecker built from a field of the main index   -->   
    <lst name="spellchecker">  
        <str name="name">default</str>  
        <!--這裏指明需要根據哪個字段的索引爲依據進行拼寫檢查。現配置 名爲 spell 的字段-->  
        <str name="field">title</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">2</int>  
        <float name="maxQueryFrequency">0.01</float>  
    </lst>
  </searchComponent>  
  <requestHandler name="/spell" class="solr.SearchHandler" startup="lazy">  
    <!--默認參數-->  
    <lst name="defaults">  
      <str name="df">title</str>  
      <str name="spellcheck.dictionary">default</str>  
      <str name="spellcheck">true</str>  
      <!-- <str name="spellcheck.extendedResults">true</str>         
      <str name="spellcheck.count">10</str>  
      <str name="spellcheck.alternativeTermCount">5</str>  
      <str name="spellcheck.maxResultsForSuggest">5</str> -->         
      <str name="spellcheck.collate">true</str>  
      <str name="spellcheck.collateExtendedResults">true</str>    
      <!-- <str name="spellcheck.maxCollationTries">10</str>  
      <str name="spellcheck.maxCollations">5</str> -->            
    </lst>  
    <arr name="last-components">  
      <str>spellcheck</str>  
    </arr>  
  </requestHandler>

3.重新創建索引使其生效.

PS:參考了另一位博主的文章http://blog.csdn.net/kevinxxw/article/details/49708311
用的分詞器不一樣，另外增加了針對拼音的智能糾錯
