Hi Mathieu,
For a simple case like that, your class bridge should work like that (from
memory):
[Indexed]
[ClassBridge(typeof(ClassBridge))]
public class Entity
{
public string Foo{get;set;}
public string Bar{get;set;}
}
public class ClassBridge:IFieldBridge
{
public void Set(string name, object value, Document document,
Field.Store store, Field.Index index, float? boost)
{
var entity = (Entity) value;
Field f = new Field("fieldName",entity.Foo + " " + entity.Bar,
Store.No, Index.Tokenized);
document.AddField(f);
}
}
The bridge basically allows you to fall back to Lucene when you need it.
