solr+jieba结巴分词

为什么选择结巴分词

  • 分词效率高
  • 词料库构建时使用的是jieba (python)

结巴分词Java版本

  • 下载
git clone https://github.com/huaban/jieba-analysis
  • 编译
cd jieba-analysis
mvn install
  • 注意
如果mvn版本较高,需要修改pom.xml文件,在plugins前面增加 

solr tokenizer版本

支持solr 6或7或更高

如果你的solr像我一样,版本比较新,需要对代码稍做修改,但改动其实不大。(根据给编译时报的错误做修改即可)

编译

./gladlew build

集成到solr

拷贝jar包到solr的目录下:server/solr-webapp/webapp/WEB-INF/lib

schema修改
