NHibernate.Search与S#arp体系结构

Question

有人设法让nhibernate.search (Lucene)使用S#arp体系结构吗？我认为我所有的连接都是正确的，除了卢克在运行我的索引方法时没有显示任何记录或索引。创建了实体的索引文件(segments.gen & segments_1)，但两者的大小都是1kb，这就解释了路克为什么没有显示数据。

我没有执行其他特定的代码让搜索工作，我是不是遗漏了一些初始化调用？我假设nhibernate会自动捕获侦听器。

在我的Web项目中，我有：

NHibernate.config

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
  <session-factory>
    <property name="connection.connection_string">Data Source=.\SQLEXPRESS;Database=MyDatabase;Integrated Security=True;</property>
    <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property>
    <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
    <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
    <property name="show_sql">true</property>
    <property name="generate_statistics">true</property>
    <property name="connection.release_mode">auto</property>
    <property name="adonet.batch_size">500</property>
    <property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property>

    <listener class='NHibernate.Search.Event.FullTextIndexEventListener, NHibernate.Search' type='post-insert'/>
    <listener class='NHibernate.Search.Event.FullTextIndexEventListener, NHibernate.Search' type='post-update'/>
    <listener class='NHibernate.Search.Event.FullTextIndexEventListener, NHibernate.Search' type='post-delete'/>
  </session-factory>
</hibernate-configuration>

Web.Config

<configSections>
  ...
  <section name="nhs-configuration" type="NHibernate.Search.Cfg.ConfigurationSectionHandler, NHibernate.Search" requirePermission="false" />
</configSections>

<nhs-configuration xmlns='urn:nhs-configuration-1.0'>
  <search-factory>
    <property name="hibernate.search.default.directory_provider">NHibernate.Search.Store.FSDirectoryProvider, NHibernate.Search</property>
    <property name="hibernate.search.default.indexBase">~\Lucene</property>
  </search-factory>
</nhs-configuration>

我的实体装饰如下：

[Indexed(Index = "Posting")] 
public class Posting : Entity
{
    [DocumentId]
    public new virtual int Id
    {
        get { return base.Id; }
        protected set { base.Id = value; }
    }

    [Field(Index.Tokenized, Store = Store.Yes)]
    [Analyzer(typeof(StandardAnalyzer))]
    public virtual string Title { get; set; }

    [Field(Index.Tokenized, Store = Store.Yes)]
    [Analyzer(typeof(StandardAnalyzer))]
    public virtual string Description { get; set; }

    public virtual DateTime CreatedDate { get; set; }
    ...
}

和我运行以下命令来创建索引

public void BuildSearchIndex()
{
    FSDirectory directory = null;
    IndexWriter writer = null;

    var type = typeof(Posting);

    var info = new DirectoryInfo(GetIndexDirectory());

    if (info.Exists)
    {
        info.Delete(true);
    }

    try
    {
        directory = FSDirectory.GetDirectory(Path.Combine(info.FullName, type.Name), true);
        writer = new IndexWriter(directory, new StandardAnalyzer(), true);
    }
    finally
    {
        if (directory != null)
        {
            directory.Close();
        }

        if (writer != null)
        {
            writer.Close();
        }
    }

    var fullTextSession = Search.CreateFullTextSession(this.Session);

    // select all Posting objects from NHibernate and add them to the Lucene index
    foreach (var instance in Session.CreateCriteria(typeof(Posting)).List<Posting>())
    {
        fullTextSession.Index(instance);
    }
}

private static string GetIndexDirectory()
{
    var nhsConfigCollection = CfgHelper.LoadConfiguration();
    var property = nhsConfigCollection.DefaultConfiguration.Properties["hibernate.search.default.indexBase"];
    var fi = new FileInfo(property);
    return Path.Combine(AppDomain.CurrentDomain.BaseDirectory, fi.Name);
}

Answer 1

找到了我的问题的答案，所以这里是为了防止其他人出现这个问题。

web.config中的NHS配置包含这样的行：

<property name="hibernate.search.default.directory_provider">NHibernate.Search.Store.FSDirectoryProvider, NHibernate.Search</property>
<property name="hibernate.search.default.indexBase">~\SearchIndex</property>

第一行应该删除，因为在这种情况下，NHS将其视为指数股票。这是众所周知的NHibernateSearch问题。

如果站点是从IIS运行的，则Network应具有搜索索引目录的所有权限。

乔丹，你在使用NHContrib的最新位元作为NHibernate.Search吗？我最近更新了我的信息，我遇到了和你一样的情况。对我来说，从七月份开始，这对我来说是可行的。但我也不能让我的索引创建。你的配置看起来是对的，和我的一样。你的索引方法看起来也不错。

约旦，现在有一种替代基于属性的Lucene.NET映射称为FluentNHibernate.Search，这个项目托管在codeplex上。

http://fnhsearch.codeplex.com/

public class BookSearchMap : DocumentMap<Book>
{
    public BookSearchMap()
    {
        Id(p => p.BookId).Field("BookId").Bridge().Guid();
        Name("Book");
        Boost(500);
        Analyzer<StandardAnalyzer>();

        Map(x => x.Title)
            .Analyzer<StandardAnalyzer>()
            .Boost(500);

        Map(x => x.Description)
            .Boost(500)
            .Name("Description")
            .Store().Yes()
            .Index().Tokenized();
    }
}
