Has anyone managed to get nhibernate.search (Lucene) to work with
S#arp Architecture? I think I have it all wired up correctly except
Luke shows no records or indexes when I run my indexing method. The
index files for the entity are created (segments.gen & segments_1) but
both are 1kb in size which explains why Luke shows no data.
I execute no other code specific to getting search to work, am I
missing some initialisation calls? I assume the listeners get picked
up automatically by nhibernate.
In my Web project I have:
**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>
**My entity is decorated as follows:**
[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; }
...
}
**And I run the following to create the index**
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);
}
