2.环境部署
1）下载地址:http://lucene.apache.org/solr/mirrors-solr-latest-redir.html
2）需要的环境：
1.Java 1.7 or greater. Some places you can get it are from Oracle, Open JDK, or IBM.
Running java -version at the command line should indicate a version number starting with 1.7.
Gnu's GCJ is not supported and does not work with Solr.
2.A Solr release.
3）官方文档
docs目录下,如下图所示：
3.教程详情
1）启动solr服务
这里使用的是官方自带的例子:start.jar ,将下载的压缩包解压到E:盘中,通过以下命令行
- E:\solr-4.8.0\example>java -jar start.jar
这里执行的是含有Solr WAR的jetty服务器和相应的配置文件
Solr can run in any Java Servlet Container of your choice, but to simplify this tutorial, the example index includes a small installation of Jetty.
To launch Jetty with the Solr WAR, and the example configs, just run the start.jar ...
此时，可以通过浏览器,输入 http://localhost:8983/solr/ 就可以查看Solr的管理界面
2）此时Solr服务已经运行，但是它并不包含任何数据，你可以通过修改Solr索引，使用POST命令的方式向Solr中增加，更新和删除信息。
3）添加数据
这
里通过以下命令行,要保证上面的solr服务一定要运行
添加数据的的数据格式，包含：
xml: application/xml,text/xml;
json: application/xml,text/json;
csv : application/csv,text/csv;
javabin: application/javabin;
向Solr中添加数据的方式，包含：
-
- Import records from a database using the Data Import Handler (DIH). 数据库
- Load a CSV file (comma separated values), including those exported by Excel or MySQL. CSV文件
- POST JSON documents JSON文档
- Index binary documents such as Word and PDF with Solr Cell (ExtractingRequestHandler).Solr格式的pdf和word字节文档
- Use SolrJ for Java or other Solr clients to programatically create documents to send to Solr.使用SolrJ或者Solr客户端编码的方式创建文档
- E:\solr-4.8.0\example\exampledoc> java -jar post.jar solr.xml monitor.xml
执行成功结果：
SimplePostTool version 1.5
Posting files to base url http://localhost:8983/solr/update using content-type a
pplication/xml..
POSTing file solr.xml
POSTing file monitor.xml
2 files indexed.

}
]
}
}
4）更新数据:
更新数据的规则：Whenever you POST commands to Solr to add a document with the same value for the uniqueKey as an existing document, it automatically replaces it for you（根据文档唯一值是否存在,替换文档的内容）
查看Solr中的文档数URL：
http://localhost:8983/solr/#/collection1/plugins/core?entry=searcher
numDocs :某个索引上的可以被搜索到的文档数
maxDocs :表示某个索引上所有的文档数目，逻辑上可能已被删除，但实现上，并没有在该索引上移除
5）删除数据：
可以使用POSTing一个删除命令到相应的URL，明确文档unique key 或者一个查询来匹配多文档。
执行下面的命令，来删除一个具体的文档：
java -Ddata=args -Dcommit=false -jar post.jar "SP2514"
