             // The expression to be added is OR(employeeType="FTE";location="Redmond")
             
                 SearchSettingGroup group = ....... // use existing or create new 
                 Keyword keyword = group.Keywords.AddKeyword("Headquarter");
             
                 var employeeContext = group.Contexts.AddContext("employee");
                 var employeeExpression = employeeContext.AddOrExpression();
                 employeeExpression.AddMatchExpression("employeeType", "FTE");
                 employeeExpression.AddMatchExpression("location", "Redmond");
                 keyword.AddSynonym("HQ",employeeContext);
