配置IKAnalyzer

修改scheme.xml

<fieldType name="text" class="solr.TextField">
		<analyzer type="index">
		  <tokenizer class="org.wltea.analyzer.solr.IKTokenizerFactory"  isMaxWordLength="false"/>
		  <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" />
		  <filter class="solr.LowerCaseFilterFactory"/>
		</analyzer>
		<analyzer type="query">
		   <tokenizer class="org.wltea.analyzer.solr.IKTokenizerFactory" isMaxWordLength="true"/>
		   <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" />
		   <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
		   <filter class="solr.LowerCaseFilterFactory"/>
		</analyzer>   
</fieldType>

索引处做最细分词，尽量让查询时能匹配

isMaxWordLength="false"

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

查询处做最大分词，尽量查找用户所需

isMaxWordLength="true"

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

配置jar包

IKAnalyzer.jar放到：work/Je.../webapp/WEB-INF/lib/IKAnalayzer.jar
IKAnalyzer.cfg.xml放到：work/Je.../webapp/WEB-INF/classes/IKAnalyzer.cfg.xml
