配置IKAnalyzer

修改scheme.xml

1. <fieldType name="text" class="solr.TextField">
   
2.                 <analyzer type="index">
   
3.                   <tokenizer class="org.wltea.analyzer.solr.IKTokenizerFactory"  isMaxWordLength="false"/>
   
4.                   <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" />
   
5.                   <filter class="solr.LowerCaseFilterFactory"/>
   
6.                 </analyzer>
   
7.                 <analyzer type="query">
   
8.                    <tokenizer class="org.wltea.analyzer.solr.IKTokenizerFactory" isMaxWordLength="true"/>
   
9.                    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" />
   
10.                    <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
    
11.                    <filter class="solr.LowerCaseFilterFactory"/>
    
12.                 </analyzer>   
    
13. </fieldType>

索引处做最细分词，尽量让查询时能匹配

1.     isMaxWordLength="false"  

复制代码

1.     <analyzer type="index">  
   
2.               <tokenizer class="org.wltea.analyzer.solr.IKTokenizerFactory"  isMaxWordLength="false"/>  
   
3.               <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" />  
   
4.               <filter class="solr.LowerCaseFilterFactory"/>  
   
5.             </analyzer>  

复制代码

查询处做最大分词，尽量查找用户所需

1.     isMaxWordLength="true"  

复制代码

1.     <analyzer type="query">  
   
2.                <tokenizer class="org.wltea.analyzer.solr.IKTokenizerFactory" isMaxWordLength="true"/>  
   
3.                <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" />  
   
4.                <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>  
   
5.                <filter class="solr.LowerCaseFilterFactory"/>  
   
6.             </analyzer>
