NHibernate.Search：基于Lucene.NET的全文索引

NHibernate.Search：基于Lucene.NET的全文索引2011-10-15 博客园孤独侠客NHibernate.Search现在是NHiberante Contrilb下面的一个还没有发布的项目,也是从 Hibernate.Search移植而来,把NHibernate和Lucene.NET结合在一起,ORM持久化对象到数据库中,Lucene.NET提供索引及查询支持.

下面在实际使用一下NHibernate.Search的使用:

由于这个项目还没有发布,它的很多特性也是一直在变化,所以现在只是以我下载的版本为准,如果你想尝试此项目,请下载最下面的代码,里面包括自己编译生成的NHibernate.Search及最新的Lucene.net相关的dll.

一.配置

1.修改你的NHibernate配置信息的地方,同样添加NHibernate.Search的配置信息.

<configSections>
<section name="hibernate-configuration"  type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate"/>
<section  name="nhs-configuration" type="NHibernate.Search.Cfg.ConfigurationSectionHandler,  NHibernate.Search" 
requirePermission="false" />
<sectionGroup  name="system.web.extensions"  type="System.Web.Configuration.SystemWebExtensionsSectionGroup, 
System.Web.Extensions,  Version=3.5.0.0, Culture=neutral,  PublicKeyToken=31BF3856AD364E35">
.....
</configSections>

需要注意的是,在NHibernate.Search之前的版本中,曾经NHibernate.Search的配置信息和NHIbernate 的放在一起.接下来,我们来看下具体的配置块:

    </session-factory>
   </hibernate-configuration>
