<!-- text_cn字段类型: 指定使用HanLP分词器,同时开启索引模式。通过solr自带的停用词过滤器,使用"stopwords.txt"(默认空白)过滤。在搜索的时候,还支持solr自带的同义词词典。-->
<fieldType name="text_cn" class="solr.TextField" positionIncrementGap="100">
    <analyzer type="index">
    <tokenizer class="com.hankcs.lucene.HanLPTokenizerFactory" enableIndexMode="true"/>
    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" />
    <!-- 取消注释可以启用索引期间的同义词词典
    <filter class="solr.SynonymFilterFactory" synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/>
    -->
    <filter class="solr.LowerCaseFilterFactory"/>
    </analyzer>
    <analyzer type="query">
    <tokenizer class="com.hankcs.lucene.HanLPTokenizerFactory" enableIndexMode="false"/>
    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" />
    <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    </analyzer>
</fieldType>
<!-- 业务系统中需要分词的字段都需要指定type为text_cn -->
<field name="my_field1" type="text_cn" indexed="true" stored="true"/>
<field name="my_field2" type="text_cn" indexed="true" stored="true"/>
