    java -version 不多说 solr 是java 开发的

    java version "1.7.0_79"
    Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
    Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)
    

     Download Solr:

    http://archive.apache.org/dist/lucene/solr/

    下载--》解压--》solr-4.10.4/example

    SimilarFacedeMacBook-Pro:example similarface$ java -jar start.jar 
    

     长长的log我也是醉了

    图形化真好看
