Solr中文分词器配置及数据检索

<blockquote><h4>导入MySQL数据</h4></blockquote>

*首先：在做检索数据之前，先将数据导入到Solr中，根据http://www.jianshu.com/p/7ce281b2be30

*然后：这次我用的是article这张表，所以在以前的配置上要改相应的配置文件（schema.xml、data-config.xml），将IKAnalyzer2012_FF_hf1.jar拷贝到/solr/WEB-INF/lib，注意：必须是IKAnalyzer2012_FF_hf1.jar，别的jar包好像不怎么好使，我试了好几个jar包。

schema.xml：

<fieldType name="text_ik" class="solr.TextField">
    <analyzer class="org.wltea.analyzer.lucene.IKAnalyzer" />
   </fieldType>
   <field name="text_ikarticle" type="text_ik" indexed="true" stored="true" required="true" /> 

其中"text_ikarticle"这个字段必须是你要中文分词的那个字段

data-config.xml：

<dataConfig>  
    <dataSource type="JdbcDataSource"  
   driver="com.mysql.jdbc.Driver"  
   url="jdbc:mysql://127.0.0.1:3306/zhangxp"  
   user="root"  
   password="123456"/>  
    <document name="search_object">   
      <entity name="article"   query="select articleID, content  from article">   
        <field column="articleID" name="id"/>
        <field column="content" name="text_ikarticle"/>
      </entity>    
   </document> 
</dataConfig>

其中field这块是添加名称转化
*其次：导入数据，导入数据如图：

使用分词查询，结果如下
