名词解释：

分面搜索（Faceted Search）--分面是指事物的多维度属性。例如一本书包含主题、作者、年代等分面。而分面搜索是指通过事物的这些属性不断筛选、过滤搜索结果的方法。可以将分面搜索看成搜索和浏览的结合

特性

• Solr 是作为一个全文检索服务器提供REST-like API.
• You feed documents into it (which is called indexing) via XML, JSON, CSV, and binary over HTTP.
• You query it through HTTP GET and receive XML, JSON, CSV, and binary results.

1. 安装

直接下载后解压缩，然后把bin目录加入path中。 注意不需要再单独安装Tomcat和Jetty了

1.1 cloud启动方式

yay@yay-ThinkPad-T470-W10DG:~/software/solr-8.5.0$ solr start -e cloud
...
后面都是采用默认值。注意一下下面这个选项：
Please provide a name for your new collection: [gettingstarted]
...
最后你会看到下面的信息：
SolrCloud example running, please visit: http://localhost:8983/solr

然后Index样例数据，我们这里用的是example/exampledocs/vidcard.xml：

yay@yay-ThinkPad-T470-W10DG:~/software/solr-8.5.0$ bin/post -c gettingstarted example/exampledocs/vidcard.xml/home/yay/software/java/jdk1.8.0_191/bin/java -classpath /home/yay/software/solr-8.5.0/dist/solr-core-8.5.0.jar -Dauto=yes -Dc=gettingstarted -Ddata=files org.apache.solr.util.SimplePostTool example/exampledocs/vidcard.xml
