Custom Property Mapping

gistfile1.cs

var doc = new EsDocument();  // Some complex object that holds dictionary of runtime user-defined fields. 
                             // doc.Fields = Dictionary<string, UserDefinedField>;
         // where UserDefinedField.Name is equal to dictionary Key 
         //     e.g.  Fields["FName"] = new UserDefinedField{Name = "FName"};
         // and UserDefinedField.Attributes is user-defined attributes that controls mapping.
         // and UserDefinedField.ContainsAttribute(attribute) returns true if such attribute set for this field.


// Here we define custom field mapping for each user-defined field in doc object.
