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
