To make Lucene use your custom analyzer in Sitefinity you need to register it in the ObjectFactory. This way it will be used both during indexing and during search. This would mean that the search index would store all characters with accents removed and during search all accents will also be removed.
Altogether you will need the following code in your Global.asax.cs:
using
System;
using
Telerik.Microsoft.Practices.Unity;
using
Telerik.Sitefinity.Abstractions;
using
Telerik.Sitefinity.Data;
using
Telerik.Sitefinity.Utilities.Lucene.Net.Analysis;
using
Telerik.Sitefinity.Utilities.Lucene.Net.Analysis.Standard;
namespace
SitefinityWebApp
{
public
class
Global : System.Web.HttpApplication
{
protected
void
Application_Start(
object
sender, EventArgs e)
{
Bootstrapper.Initialized +=
this
.Bootstrapper_Initialized;
}
private
void
Bootstrapper_Initialized(
object
sender, ExecutedEventArgs e)
{
if
(e.CommandName !=
"Bootstrapped"
)
return
;
ObjectFactory.Container.RegisterType<Analyzer, AccentInsensitiveAnalyzer>(
new
ContainerControlledLifetimeManager(),
new
InjectionConstructor(
new
InjectionParameter<
string
[]>(
null
)));
}
}
public
class
AccentInsensitiveAnalyzer : StandardAnalyzer
{
public
AccentInsensitiveAnalyzer(
string
[] stopWords)
:
base
(stopWords)
{
}
public
override
TokenStream TokenStream(
string
fieldName, System.IO.TextReader reader)
{
TokenStream stream =
new
StandardTokenizer(reader);
stream =
new
StandardFilter(stream);
stream =
new
ASCIIFoldingFilter(stream);
return
stream;
}
}
}
