SOLR技术文档
1. 了解lucene 原理,全文搜索概念,参考(http://wishlife.iteye.com/category/30179
) .建立自己的索引库.
2. 了解solr参考(http://www.ibm.com/developerworks/cn/java/j-solr1/
, http://www.ibm.com/developerworks/cn/java/j-solr2/
).并下载实例程序.
3. 搭建SOLR服务器
3.1 官方下载 apache-solr-1.3.0.zip 和tomcat5.5
3.2 将apache-solr-1.3.0\example\webapps\solr.war部署有 tomcat 下
3.4 将apache-solr-1.3.0\example\solr 下所有文件复制到e:/tomcat/solr下
3.5 启动 tomcat -> 浏览http://localhost:8080/solr/admin/ 能访问Solr Admin 页面说明Solr 服务器设置成功.

4. 为Solr 创建索引库
4.1 在 e:/tomcat/solr 目录下新建名为data 的文件夹,再在data 下新建index名为 文件夹
4.2 将lucene 创建好的索引放入e:/tomcat/solr/data/index 下
5. Solr 索引设置
5.1 在e:/tomcat/solr /conf 下solrconfig.xml, schema.xml
<?xml version="1.0" ?>
<schema name="metasearch" version="1.1">
<types>
<!-- not analyzed-->
<fieldType name="string" class="solr.StrField"
sortMissingLast="true" omitNorms="true" />
<!--
Numeric field types that manipulate the value into a string value
that isn't human-readable in its internal form, but with a
lexicographic ordering the same as the numeric ordering, so that
range queries work correctly.
