 You can also create mappings on the fly:
 
-	var typeMapping = new TypeMapping(Guid.NewGuid().ToString("n"));
-	var property = new TypeMappingProperty
+	var indexDefinition = new RootObjectMapping
 	{
-		Type = "multi_field"

 ## Multifield Mapping
 To create multifield type you can use following example. 
 
 	var result = this._client.Map<ElasticsearchProject>(m => m
 		.Properties(props => props
-		.MultiField(s => s
+		.String(s => s
 		.Name(p => p.Name)
 		.Path(MultiFieldMappingPath.Full)
+		.Index(FieldIndexOption.not_analyzed)
 		.Fields(pprops => pprops
-			.String(ps => ps.Name(p => p.Name).Index(FieldIndexOption.not_analyzed))
 			.String(ps => ps.Name(p => p.Name.Suffix("searchable")).Index(FieldIndexOption.analyzed))
 		)
