搞定了中文分词下一个就是要来搞定拼音分词了，拼音分词有分为全拼和简拼

PS：8.0.0版本已经发布，本文使用此时较为稳定的7.7.1版本

一，全拼分词

代码语言：javascript复制
> wget http://files.cnblogs.com/files/wander1129/pinyin.zip
> unzip pinyin.zip
> mv pinyin4j-2.5.0.jar  server/solr-webapp/webapp/WEB-INF/lib
> mv pinyinAnalyzer4.3.1.jar  server/solr-webapp/webapp/WEB-INF/lib
代码语言：javascript复制
> vim server/solr/new_core/conf/managed-schema

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

自制分词规则

代码语言：javascript复制
> webapps/solr/WEB-INF/classes/
> cd /usr/local/solr-7.7.1/server/solr-webapp/webapp/WEB-INF
> mkdir classes
代码语言：javascript复制
> wget http://pic.w-blog.cn/ikanalyzer-solr5.zip
> unzip ikanalyzer-solr5.zip 
> cd ikanalyzer-solr5/
> mv ext.dic ../server/solr-webapp/webapp/WEB-INF/classes/
> mv IKAnalyzer.cfg.xml ../server/solr-webapp/webapp/WEB-INF/classes/
> mv stopword.dic ../server/solr-webapp/webapp/WEB-INF/classes/
代码语言：javascript复制
> vim ext.dic
