Django之站内搜索-Solr,Haystack

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

schema.xml默认写下面的：

<?xml version="1.0" ?>
   <schema name="default" version="1.5">
   </schema>

上面怎么做，bitch ，mkdir and vim

 

 

pip install django-haystack==2.4.0

pip install pysolr==3.3.2

settings.py
